Scientists don’t often publish when they confirm an article is correct. Knowing a few mathematicians, probably they see no need to do that. They checked the proof, it was ok and that’s it.
Either way, many of those proofs come with a computer program which checks and confirms the proof is correct.
I trust that an expert mathematician talking about such things has reviewed a few of those articles and has checked the proof.
You may not do that; check the proof yourself or pay a mathematician to do it for you.

This sounds like something you outright made up.
Classical unsolved math problems have rewards.
Mathematics absolutely have peer review:

Indeed peer reviewed exists in mathematics. Now, whether it is common practice to publish stuff on arxiv and leave it there is another thing.
I don’t know about mathematics, but I know plenty other Fields where it is common practice to just publish on arxiv.
