Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599568, here are decompositions:

5 + 31599563 = 31599568
17 + 31599551 = 31599568
137 + 31599431 = 31599568
179 + 31599389 = 31599568
227 + 31599341 = 31599568
467 + 31599101 = 31599568
509 + 31599059 = 31599568
641 + 31598927 = 31599568

Showing the first eight; more decompositions exist.
