Given an *odd* prime p, there exist primes q, r such that p+q+r = qr. This is more profitably written as
Given an *odd* prime p, there exist primes q, r such that p+q+r = qr.
This is more profitably written as
p+1 = (q-1)(r-1) So if q=2 then p,r must be twin primes If both q and r are odd, then p = 3 mod 4. Victor
