Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459000, here are decompositions:

17 + 31458983 = 31459000
47 + 31458953 = 31459000
137 + 31458863 = 31459000
179 + 31458821 = 31459000
239 + 31458761 = 31459000
281 + 31458719 = 31459000
311 + 31458689 = 31459000
563 + 31458437 = 31459000

Showing the first eight; more decompositions exist.
