Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596084, here are decompositions:

17 + 31596067 = 31596084
43 + 31596041 = 31596084
101 + 31595983 = 31596084
211 + 31595873 = 31596084
251 + 31595833 = 31596084
277 + 31595807 = 31596084
307 + 31595777 = 31596084
313 + 31595771 = 31596084

Showing the first eight; more decompositions exist.
