Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606076, here are decompositions:

163 + 31605913 = 31606076
199 + 31605877 = 31606076
349 + 31605727 = 31606076
379 + 31605697 = 31606076
457 + 31605619 = 31606076
499 + 31605577 = 31606076
727 + 31605349 = 31606076
757 + 31605319 = 31606076

Showing the first eight; more decompositions exist.
