If we meet aliens, we should exchange Mersenne primes.

  To them, that would be like someone wants to exchange integers with us. - Fifteen THOUSAND! - Uuuh...

    You assume that they will be advanced enough to come to us. What if we find them in Europa or Titan?

      Then we will probably not ask them to exchange Mersenne primes with us either. :-)

  ...or claim that "my prime is bigger than yours" :)
