Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459030, here are decompositions:

11 + 31459019 = 31459030
47 + 31458983 = 31459030
107 + 31458923 = 31459030
167 + 31458863 = 31459030
233 + 31458797 = 31459030
269 + 31458761 = 31459030
311 + 31458719 = 31459030
443 + 31458587 = 31459030

Showing the first eight; more decompositions exist.
