Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459776, here are decompositions:

17 + 31459759 = 31459776
43 + 31459733 = 31459776
53 + 31459723 = 31459776
59 + 31459717 = 31459776
67 + 31459709 = 31459776
79 + 31459697 = 31459776
97 + 31459679 = 31459776
109 + 31459667 = 31459776

Showing the first eight; more decompositions exist.
