Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459814, here are decompositions:

7 + 31459807 = 31459814
97 + 31459717 = 31459814
163 + 31459651 = 31459814
181 + 31459633 = 31459814
193 + 31459621 = 31459814
457 + 31459357 = 31459814
523 + 31459291 = 31459814
613 + 31459201 = 31459814

Showing the first eight; more decompositions exist.
