Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459182, here are decompositions:

31 + 31459151 = 31459182
59 + 31459123 = 31459182
71 + 31459111 = 31459182
89 + 31459093 = 31459182
109 + 31459073 = 31459182
113 + 31459069 = 31459182
151 + 31459031 = 31459182
163 + 31459019 = 31459182

Showing the first eight; more decompositions exist.
