Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459110, here are decompositions:

17 + 31459093 = 31459110
37 + 31459073 = 31459110
41 + 31459069 = 31459110
47 + 31459063 = 31459110
79 + 31459031 = 31459110
127 + 31458983 = 31459110
157 + 31458953 = 31459110
173 + 31458937 = 31459110

Showing the first eight; more decompositions exist.
