Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459710, here are decompositions:

13 + 31459697 = 31459710
31 + 31459679 = 31459710
43 + 31459667 = 31459710
59 + 31459651 = 31459710
89 + 31459621 = 31459710
101 + 31459609 = 31459710
157 + 31459553 = 31459710
193 + 31459517 = 31459710

Showing the first eight; more decompositions exist.
