Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459844, here are decompositions:

37 + 31459807 = 31459844
127 + 31459717 = 31459844
193 + 31459651 = 31459844
211 + 31459633 = 31459844
223 + 31459621 = 31459844
457 + 31459387 = 31459844
487 + 31459357 = 31459844
523 + 31459321 = 31459844

Showing the first eight; more decompositions exist.
