Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612776, here are decompositions:

17 + 31612759 = 31612776
23 + 31612753 = 31612776
29 + 31612747 = 31612776
37 + 31612739 = 31612776
43 + 31612733 = 31612776
47 + 31612729 = 31612776
109 + 31612667 = 31612776
113 + 31612663 = 31612776

Showing the first eight; more decompositions exist.
