Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459586, here are decompositions:

199 + 31459387 = 31459586
229 + 31459357 = 31459586
463 + 31459123 = 31459586
523 + 31459063 = 31459586
619 + 31458967 = 31459586
673 + 31458913 = 31459586
757 + 31458829 = 31459586
787 + 31458799 = 31459586

Showing the first eight; more decompositions exist.
