It would be worth at least $1 million.

More seriously, "mere" correctness serves the valuable function that it 
will convince the mathematical community to study the proof, and extract 
whatever value can be extracted from it.  The issue with a purported 
solution of a famous problem that is difficult to read is that the 
potential reader has to deal with the nagging suspicion that the proof is 
wrong and therefore studying it will be largely a waste of time.
