Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459124, here are decompositions:

13 + 31459111 = 31459124
31 + 31459093 = 31459124
61 + 31459063 = 31459124
157 + 31458967 = 31459124
211 + 31458913 = 31459124
223 + 31458901 = 31459124
337 + 31458787 = 31459124
421 + 31458703 = 31459124

Showing the first eight; more decompositions exist.
