Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15556, here are decompositions:

5 + 15551 = 15556
29 + 15527 = 15556
59 + 15497 = 15556
83 + 15473 = 15556
89 + 15467 = 15556
113 + 15443 = 15556
173 + 15383 = 15556
179 + 15377 = 15556

Showing the first eight; more decompositions exist.
