Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459118, here are decompositions:

7 + 31459111 = 31459118
151 + 31458967 = 31459118
181 + 31458937 = 31459118
211 + 31458907 = 31459118
331 + 31458787 = 31459118
409 + 31458709 = 31459118
421 + 31458697 = 31459118
487 + 31458631 = 31459118

Showing the first eight; more decompositions exist.
