The grue lurks in the darkest places of the earth. Its favorite diet is adventurers, but its insatiable appetite is tempered by its fear of light. No grue has ever been seen by the light of day, and few have survived its fearsome jaws to tell the tale.

Any hex can be converted into a private key, it's just a large number. However, if you are trying to get the private key of an address, it is not possible to do so.

To the private key for that address?

No.

Can't be done.

Yep. You are missing the concepts of RIPEMD160, SHA256, and ECDSA, all of which prevent you from working backwards from a bitcoin address to a private key.

Since the OP is looking for education, RIPEMD160, SHA256 are hash functions: https://en.wikipedia.org/wiki/Hash_function

ECDSA is an algorithm for digital signatures, one aspect of assymetric key cryptography: https://en.wikipedia.org/wiki/Public-key_cryptography

Good luck!
