Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459258, here are decompositions:

41 + 31459217 = 31459258
59 + 31459199 = 31459258
107 + 31459151 = 31459258
227 + 31459031 = 31459258
239 + 31459019 = 31459258
461 + 31458797 = 31459258
557 + 31458701 = 31459258
569 + 31458689 = 31459258

Showing the first eight; more decompositions exist.
