Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596918, here are decompositions:

5 + 31596913 = 31596918
11 + 31596907 = 31596918
19 + 31596899 = 31596918
29 + 31596889 = 31596918
37 + 31596881 = 31596918
61 + 31596857 = 31596918
71 + 31596847 = 31596918
79 + 31596839 = 31596918

Showing the first eight; more decompositions exist.
