Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13688, here are decompositions:

7 + 13681 = 13688
19 + 13669 = 13688
61 + 13627 = 13688
97 + 13591 = 13688
151 + 13537 = 13688
211 + 13477 = 13688
271 + 13417 = 13688
277 + 13411 = 13688

Showing the first eight; more decompositions exist.
