This part of your post "19...................." is more important, but you are hiding it, so....
And I think pretty much addresses and private key ranges have no relation, it is useless to look for addresses when you do operations on public keys.
Besides, you have to tell us whether this key is -n or +n, but if you give me the key you subtracted from #125 which starts with 19, I could tell you the -n or +n of this key

so bro, because i told you 3 or 4 times how it work, i think you dont know enough how it works the substraction,, its simple
if you substract 125 to lower range , its only you put -s in commande keysub line ... so you will get this
pubkey # + 11000000
pubkey # + 11001000
pubkey # + 11002000
pubkey #target
so, the search range here is

? you know it,, its 11001000-11000000 =1000
we do this -bsgs -m xpoint ... range 1000:1ffff
or anything you are using to searche the range,,, thats how you substract the range,,,
if you are using -a command that means bro,,
125 +++ ,, you are in bigger range,, maybe in 2f300000000000000000000000000000 or 3f or 4f
if you want to substract you only use -s
im teaching you because i know you didint get it,,, and if you did get it ,,, when i post the public key of 13zb1hq. and told you guys its 66 ,,, its obious its -s you cant ask me if its a + or - ........ bro +++++ that means lower range that means the commande is -s ,,, dont use -a ,, if you substract the puzzle 125 from fffffffffffffffffffffffffffffffebaaedce6af48a03bbfd25e8cc1e825e6 to 1 to 125,, you only use -s,,, with this methode, you are substracting lowering the range from zero to 125,, if you do + and - ,, you wont ever be close to anything and you will pass your lifetime doing this on your txt file trying to solve the public key hexes
its obious you didint figure it out how it works because you are working on public keys directly, you are seeing the hexes all around your txt file and you dont see any address
and dont be angry or anything im just trying to help you here.
