Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459914, here are decompositions:

23 + 31459891 = 31459914
61 + 31459853 = 31459914
67 + 31459847 = 31459914
107 + 31459807 = 31459914
181 + 31459733 = 31459914
191 + 31459723 = 31459914
197 + 31459717 = 31459914
263 + 31459651 = 31459914

Showing the first eight; more decompositions exist.
