Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459964, here are decompositions:

73 + 31459891 = 31459964
157 + 31459807 = 31459964
241 + 31459723 = 31459964
313 + 31459651 = 31459964
331 + 31459633 = 31459964
577 + 31459387 = 31459964
607 + 31459357 = 31459964
643 + 31459321 = 31459964

Showing the first eight; more decompositions exist.
