Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459048, here are decompositions:

17 + 31459031 = 31459048
29 + 31459019 = 31459048
227 + 31458821 = 31459048
251 + 31458797 = 31459048
347 + 31458701 = 31459048
359 + 31458689 = 31459048
461 + 31458587 = 31459048
521 + 31458527 = 31459048

Showing the first eight; more decompositions exist.
