Rather than searching for addresses you should search for pubkey with funds (there are a lot) with a kangaroo or rho program.
It will be much faster, ~2.4e19 years with rho or kangaroo against ~9e28 years with address finder (on 256xTelsa V100)

Do not use my kangaroo program which is limited to 125 bit range key search !
Edit:
For instance this pubkey:
02545d2c25b98ec8827f2d9bee22b7a9fb98091b2008bc45b3b806d44624dc038c (1HQ3Go3ggs8pFnXuHVHRytPCq5fGG8Hbhx)
hold 69370BTC
I know you know Jean Luc but for the "get rich fast" newbies out there: just because the public key is known doesn't mean you will be able to find the private key by bruteforcing. The only time this has been done is with specific puzzle-transactions in which along with the public key the search space is predefined.
