Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459150, here are decompositions:

17 + 31459133 = 31459150
131 + 31459019 = 31459150
167 + 31458983 = 31459150
197 + 31458953 = 31459150
227 + 31458923 = 31459150
353 + 31458797 = 31459150
389 + 31458761 = 31459150
431 + 31458719 = 31459150

Showing the first eight; more decompositions exist.
