Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459944, here are decompositions:

7 + 31459937 = 31459944
13 + 31459931 = 31459944
53 + 31459891 = 31459944
97 + 31459847 = 31459944
137 + 31459807 = 31459944
211 + 31459733 = 31459944
227 + 31459717 = 31459944
277 + 31459667 = 31459944

Showing the first eight; more decompositions exist.
