If you’re going to be rude and arrogant, then the level of knowledge you exhibit has to match. SHA-256 decryption would be a front of the world achievement because it would be redefining foundational mathematics since it’s not an encryption algorithm. The words you’d be looking for are either a collision of SHA-256 or breaking encryption algorithms like AES, RSA, ECC etc. sha-256 is used in the construction of certain encryption algorithms as a primitive but by itself never encrypts anything. If it did you’ve also got middleout compression invented since you could encrypt arbitrary length input into 256 bits of output.
