%N A231903 Even numbers which are the sum of two different primes > 3 in exactly one way.
%C A231903 Conjecture: there are no more numbers > 62 in the sequence.
%C A231903 Remark that the two primes are one of a twin primes pair and a pair of twin primes for 12=5+7.
%C A231903 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 A231903 10=3+7=5+5 not in the sequence (not >3 or not different),
%e A231903 12=5+7, 12 first in the sequence,
%e A231903 14=3+11=7+7 not in the sequence.
