Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600776, here are decompositions:

5 + 31600771 = 31600776
23 + 31600753 = 31600776
43 + 31600733 = 31600776
59 + 31600717 = 31600776
73 + 31600703 = 31600776
83 + 31600693 = 31600776
107 + 31600669 = 31600776
113 + 31600663 = 31600776

Showing the first eight; more decompositions exist.
