Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495094, here are decompositions:

31 + 31495063 = 31495094
151 + 31494943 = 31495094
157 + 31494937 = 31495094
277 + 31494817 = 31495094
313 + 31494781 = 31495094
331 + 31494763 = 31495094
373 + 31494721 = 31495094
457 + 31494637 = 31495094

Showing the first eight; more decompositions exist.
