Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495044, here are decompositions:

41 + 31495003 = 31495044
101 + 31494943 = 31495044
107 + 31494937 = 31495044
137 + 31494907 = 31495044
157 + 31494887 = 31495044
227 + 31494817 = 31495044
263 + 31494781 = 31495044
277 + 31494767 = 31495044

Showing the first eight; more decompositions exist.
