Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459056, here are decompositions:

37 + 31459019 = 31459056
73 + 31458983 = 31459056
89 + 31458967 = 31459056
103 + 31458953 = 31459056
149 + 31458907 = 31459056
193 + 31458863 = 31459056
227 + 31458829 = 31459056
257 + 31458799 = 31459056

Showing the first eight; more decompositions exist.
