Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15388, here are decompositions:

5 + 15383 = 15388
11 + 15377 = 15388
29 + 15359 = 15388
59 + 15329 = 15388
89 + 15299 = 15388
101 + 15287 = 15388
227 + 15161 = 15388
239 + 15149 = 15388

Showing the first eight; more decompositions exist.
