Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 112728, here are decompositions:

37 + 112691 = 112728
41 + 112687 = 112728
71 + 112657 = 112728
107 + 112621 = 112728
127 + 112601 = 112728
139 + 112589 = 112728
151 + 112577 = 112728
157 + 112571 = 112728

Showing the first eight; more decompositions exist.
