Solve The Beal Conjecture and win $100,000

The Beal conjecture is one of those odd math problems that may be
unsolvable. But if the beal conjecture is solved it is worth a lot of
money. Beal's conjecture was discovered by a Banker in Texas.

BEAL'S CONJECTU If Ax + By = Cz, where A, B, C, x, y and z are
positive integers and x, y and z are all greater than 2, then A, B and
C must have a common prime factor.

I tried to solve the beal conjecture but the beal conjecture is beyond
my math skills.

Are there any other unclaimed puzzle prizes like the beal conjecture
out there that aren't as math intensive as the beal conjecture.
