Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31605362, here are decompositions:

13 + 31605349 = 31605362
43 + 31605319 = 31605362
181 + 31605181 = 31605362
193 + 31605169 = 31605362
223 + 31605139 = 31605362
499 + 31604863 = 31605362
619 + 31604743 = 31605362
631 + 31604731 = 31605362

Showing the first eight; more decompositions exist.
