Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459682, here are decompositions:

3 + 31459679 = 31459682
31 + 31459651 = 31459682
61 + 31459621 = 31459682
73 + 31459609 = 31459682
283 + 31459399 = 31459682
421 + 31459261 = 31459682
571 + 31459111 = 31459682
613 + 31459069 = 31459682

Showing the first eight; more decompositions exist.
