M is the smallest possible sum for a set of four distinct primes such that the sum of any three is prime - (p1,p2,p3,p4}.
N is the smallest possible sum for a set of six distinct primes such that the sum of any five is prime - (q1,q2,q3,q4,q5,q6}.

Find M & N and the corresponding sets.

Thanks, Steve Herman.  I was so busy mod-sixing that I missed the simpler proof.
