Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596788, here are decompositions:

19 + 31596769 = 31596788
31 + 31596757 = 31596788
37 + 31596751 = 31596788
79 + 31596709 = 31596788
109 + 31596679 = 31596788
127 + 31596661 = 31596788
151 + 31596637 = 31596788
277 + 31596511 = 31596788

Showing the first eight; more decompositions exist.
