Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606166, here are decompositions:

79 + 31606087 = 31606166
409 + 31605757 = 31606166
439 + 31605727 = 31606166
547 + 31605619 = 31606166
727 + 31605439 = 31606166
919 + 31605247 = 31606166
937 + 31605229 = 31606166
997 + 31605169 = 31606166

Showing the first eight; more decompositions exist.
