Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459634, here are decompositions:

13 + 31459621 = 31459634
277 + 31459357 = 31459634
313 + 31459321 = 31459634
373 + 31459261 = 31459634
433 + 31459201 = 31459634
523 + 31459111 = 31459634
541 + 31459093 = 31459634
571 + 31459063 = 31459634

Showing the first eight; more decompositions exist.
