Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 56728, here are decompositions:

17 + 56711 = 56728
41 + 56687 = 56728
47 + 56681 = 56728
131 + 56597 = 56728
137 + 56591 = 56728
197 + 56531 = 56728
227 + 56501 = 56728
239 + 56489 = 56728

Showing the first eight; more decompositions exist.
