    It is not a statement. It is a discovery.

    I know. A discovery can be summarised in a statement.

    One word: Meh.

    Sure, you can just go program and find mersenne primes, but what would be more interesting is finding an underlying connection to literally every other branch of mathematics. Now that, would be a huge deal, and probably revolutionise the way modern mathematics is held together.
