Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459796, here are decompositions:

37 + 31459759 = 31459796
73 + 31459723 = 31459796
79 + 31459717 = 31459796
163 + 31459633 = 31459796
397 + 31459399 = 31459796
409 + 31459387 = 31459796
439 + 31459357 = 31459796
457 + 31459339 = 31459796

Showing the first eight; more decompositions exist.
