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)
