Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13664, here are decompositions:

31 + 13633 = 13664
37 + 13627 = 13664
67 + 13597 = 13664
73 + 13591 = 13664
97 + 13567 = 13664
127 + 13537 = 13664
151 + 13513 = 13664
223 + 13441 = 13664

Showing the first eight; more decompositions exist.
