Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459948, here are decompositions:

11 + 31459937 = 31459948
17 + 31459931 = 31459948
89 + 31459859 = 31459948
101 + 31459847 = 31459948
239 + 31459709 = 31459948
251 + 31459697 = 31459948
269 + 31459679 = 31459948
281 + 31459667 = 31459948

Showing the first eight; more decompositions exist.
