Looks tempting to crack

It does, but I still haven't understand the method/how does one go to attempt and find the solution to the puzzle

One thing I noticed:
The first address in the transaction is tagged on blockchain.info with "1st Bitcoin Address Compressed".
So probably this transaction was done by the Bitcoin devs? or even... satoshi?
This hardly has anything to to with any of them.
looks really easy to crack
why would reward be so high
Suggestions are always welcome.
