Sieving freakishly big MMs (was "World record" phone number?)
Isn't the notion rendered nonsense by multiplying all the primes up to (say) a billion together and adding 1?

That is behind the proof that there are an infinite number of primes.

There are tons of examples in math where we are looking for the interesting cases and ignoring the "trivial" cases which this is. Like the "nontrivial Riemann zeta function zeros".

I can say with 100% certainty that the smallest prime factor of M(M43112609) is a world record prime, but without an explicit demonstration of such a factor, that is meaningless.
