Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15586, here are decompositions:

3 + 15583 = 15586
5 + 15581 = 15586
17 + 15569 = 15586
59 + 15527 = 15586
89 + 15497 = 15586
113 + 15473 = 15586
173 + 15413 = 15586
227 + 15359 = 15586

Showing the first eight; more decompositions exist.
