Conjecture: there are no more numbers > 62 in the sequence.
Remark that the two primes are one of a twin primes pair and a pair of twin primes for 12=5+7.
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.
EXAMPLE
10=3+7=5+5 not in the sequence (not >3 or not different),
12=5+7, 12 first in the sequence,
14=3+11=7+7 not in the sequence.
PROG
(PARI) is_A231903(n)={my(s=0); forprime(p=5, n\2-1, isprime(n-p)&&s++>1&&return); s} \\ - M. F. Hasler, Nov 22 2013
