Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459376, here are decompositions:

19 + 31459357 = 31459376
37 + 31459339 = 31459376
283 + 31459093 = 31459376
307 + 31459069 = 31459376
313 + 31459063 = 31459376
409 + 31458967 = 31459376
439 + 31458937 = 31459376
463 + 31458913 = 31459376

Showing the first eight; more decompositions exist.
