Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459012, here are decompositions:

29 + 31458983 = 31459012
59 + 31458953 = 31459012
89 + 31458923 = 31459012
149 + 31458863 = 31459012
191 + 31458821 = 31459012
251 + 31458761 = 31459012
293 + 31458719 = 31459012
311 + 31458701 = 31459012

Showing the first eight; more decompositions exist.
