Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599816, here are decompositions:

5 + 31599811 = 31599816
7 + 31599809 = 31599816
43 + 31599773 = 31599816
89 + 31599727 = 31599816
109 + 31599707 = 31599816
113 + 31599703 = 31599816
163 + 31599653 = 31599816
167 + 31599649 = 31599816

Showing the first eight; more decompositions exist.
