Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596328, here are decompositions:

11 + 31596317 = 31596328
17 + 31596311 = 31596328
359 + 31595969 = 31596328
461 + 31595867 = 31596328
521 + 31595807 = 31596328
557 + 31595771 = 31596328
641 + 31595687 = 31596328
761 + 31595567 = 31596328

Showing the first eight; more decompositions exist.
