Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596412, here are decompositions:

11 + 31596401 = 31596412
101 + 31596311 = 31596412
269 + 31596143 = 31596412
293 + 31596119 = 31596412
383 + 31596029 = 31596412
443 + 31595969 = 31596412
641 + 31595771 = 31596412
839 + 31595573 = 31596412

Showing the first eight; more decompositions exist.
