I know it was a typo, which is why in the data below I correct that typo. And with the typo corrected I do find counterexamples. Check again please.

Subject: RE: [PrimeNumbers] Goldbach

These messages about Goldbach's Conjecture are not

supposed to be to this mailing list (also the Riemann Hypothesis).

There are separate mailing lists for these.

Kermit says.

Milton! You surprise me.

Goldbach's conjecture IS about prime numbers. It's doesn't matter that

there exist mailing lists specifically about Goldbach's conjecture.
