Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607796, here are decompositions:

5 + 31607791 = 31607796
7 + 31607789 = 31607796
13 + 31607783 = 31607796
79 + 31607717 = 31607796
107 + 31607689 = 31607796
109 + 31607687 = 31607796
113 + 31607683 = 31607796
167 + 31607629 = 31607796

Showing the first eight; more decompositions exist.
