you do not know the private even or odd.
you can find the public key even or odd.

2548/2 = 1274
2548/10 = 254.8
2548/100= 25.48
2548/1000= 2.548

next
10 - 2.548 = 7.452
....

Looks like a math from primary school Grin

Do you write in English by yourself or you use translator? It is difficult to understand you because you do not use full sentences, just a few words all the time.
At the end - what do you say you are able to accomplish? Find private key from public key (on any range)? What database you have - database of public keys in some range? Please, for the moment, think what you want to write and write it down slowly and carefully, maybe use google translator if you need.
Huh

I had understand his idea.....
but #120 private key is unknown number...this method must know unknown private key number is even or odd ..
#120 ( we can't know private key is even or odd from public key )

all point lies on the elliptic curve

if we can know unknown number is even or odd
( G public key only use + - * / Addition, subtraction, multiplication and division operator , can't use modulus % )
bitcoin private key will can crack from a public key ....
