Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459936, here are decompositions:

5 + 31459931 = 31459936
83 + 31459853 = 31459936
89 + 31459847 = 31459936
107 + 31459829 = 31459936
227 + 31459709 = 31459936
239 + 31459697 = 31459936
257 + 31459679 = 31459936
269 + 31459667 = 31459936

Showing the first eight; more decompositions exist.
