Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460188, here are decompositions:

59 + 31460129 = 31460188
239 + 31459949 = 31460188
251 + 31459937 = 31460188
257 + 31459931 = 31460188
359 + 31459829 = 31460188
479 + 31459709 = 31460188
491 + 31459697 = 31460188
509 + 31459679 = 31460188

Showing the first eight; more decompositions exist.
