Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459850, here are decompositions:

3 + 31459847 = 31459850
43 + 31459807 = 31459850
127 + 31459723 = 31459850
199 + 31459651 = 31459850
229 + 31459621 = 31459850
241 + 31459609 = 31459850
463 + 31459387 = 31459850
727 + 31459123 = 31459850

Showing the first eight; more decompositions exist.
