Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600836, here are decompositions:

13 + 31600823 = 31600836
19 + 31600817 = 31600836
37 + 31600799 = 31600836
53 + 31600783 = 31600836
83 + 31600753 = 31600836
103 + 31600733 = 31600836
167 + 31600669 = 31600836
173 + 31600663 = 31600836

Showing the first eight; more decompositions exist.
