Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596406, here are decompositions:

3 + 31596403 = 31596406
5 + 31596401 = 31596406
89 + 31596317 = 31596406
113 + 31596293 = 31596406
197 + 31596209 = 31596406
263 + 31596143 = 31596406
599 + 31595807 = 31596406
683 + 31595723 = 31596406

Showing the first eight; more decompositions exist.
