Given this contest can presumably go on infinitely long, what is the ultimate point of the contest? Is there some kind of theoretical or practical benefit to discovering a new Mersenne prime?

prove it

It's well established that there are infinite prime numbers, for example https://www-users.york.ac.uk/~ss44/cyc/p/primeprf.htm

Should be able to trivially extend that logic to Mersenne Primes then, 'presumably'

It’s not.

The traditional proof that there are an infinite number of primes relies on unique prime factorisation- i.e for any number, n, there is a unique set of primes p1, p2, p3, … etc. where p1 * p2 * p3 * … = n

For instance 88 = 2 * 2 * 2 * 11, 42 = 2 * 3 * 7

It’s worth reading the proof if you haven’t - it’s comprehensible with high school maths.

No such property exists for Mersenne primes, so we can’t trivially extend it. Many proofs of the properties of prime numbers are difficult because they, by definition, actively resist patterns.
