Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596308, here are decompositions:

157 + 31596151 = 31596308
181 + 31596127 = 31596308
241 + 31596067 = 31596308
379 + 31595929 = 31596308
439 + 31595869 = 31596308
577 + 31595731 = 31596308
607 + 31595701 = 31596308
727 + 31595581 = 31596308

Showing the first eight; more decompositions exist.
