%S 12,16,20,22,26,32,38,62
%N Even numbers which are the sum of two different primes > 3 in exactly one way.
%C Conjecture: there are no more numbers > 62 in the sequence.
%C Remark that the two primes are one of a twin primes pair and a pair of twin primes for 12=5+7.
%C The pairs of primes are : 12=5+7, 16=5+11, 20=7+13, 22=5+17, 26=7+19, 32=13+19, 38=7+31, 62=19+43.
%e 10=3+7=5+5 not in the sequence (not >3 or not different),
%e 12=5+7, 12 first in the sequence,
%e 14=3+11=7+7 not in the sequence.
