Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459862, here are decompositions:

3 + 31459859 = 31459862
13 + 31459849 = 31459862
103 + 31459759 = 31459862
139 + 31459723 = 31459862
211 + 31459651 = 31459862
229 + 31459633 = 31459862
241 + 31459621 = 31459862
463 + 31459399 = 31459862

Showing the first eight; more decompositions exist.
