Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606196, here are decompositions:

109 + 31606087 = 31606196
283 + 31605913 = 31606196
373 + 31605823 = 31606196
439 + 31605757 = 31606196
499 + 31605697 = 31606196
577 + 31605619 = 31606196
613 + 31605583 = 31606196
619 + 31605577 = 31606196

Showing the first eight; more decompositions exist.
