Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596316, here are decompositions:

5 + 31596311 = 31596316
23 + 31596293 = 31596316
107 + 31596209 = 31596316
173 + 31596143 = 31596316
197 + 31596119 = 31596316
347 + 31595969 = 31596316
443 + 31595873 = 31596316
449 + 31595867 = 31596316

Showing the first eight; more decompositions exist.
