Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599814, here are decompositions:

3 + 31599811 = 31599814
5 + 31599809 = 31599814
41 + 31599773 = 31599814
47 + 31599767 = 31599814
53 + 31599761 = 31599814
107 + 31599707 = 31599814
131 + 31599683 = 31599814
251 + 31599563 = 31599814

Showing the first eight; more decompositions exist.
