Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15628, here are decompositions:

47 + 15581 = 15628
59 + 15569 = 15628
101 + 15527 = 15628
131 + 15497 = 15628
167 + 15461 = 15628
227 + 15401 = 15628
251 + 15377 = 15628
269 + 15359 = 15628

Showing the first eight; more decompositions exist.
