Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599826, here are decompositions:

3 + 31599823 = 31599826
17 + 31599809 = 31599826
53 + 31599773 = 31599826
59 + 31599767 = 31599826
173 + 31599653 = 31599826
197 + 31599629 = 31599826
227 + 31599599 = 31599826
263 + 31599563 = 31599826

Showing the first eight; more decompositions exist.
