Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459962, here are decompositions:

13 + 31459949 = 31459962
31 + 31459931 = 31459962
71 + 31459891 = 31459962
103 + 31459859 = 31459962
109 + 31459853 = 31459962
113 + 31459849 = 31459962
229 + 31459733 = 31459962
239 + 31459723 = 31459962

Showing the first eight; more decompositions exist.
