Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596356, here are decompositions:

163 + 31596193 = 31596356
193 + 31596163 = 31596356
229 + 31596127 = 31596356
307 + 31596049 = 31596356
349 + 31596007 = 31596356
367 + 31595989 = 31596356
373 + 31595983 = 31596356
487 + 31595869 = 31596356

Showing the first eight; more decompositions exist.
