Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606328, here are decompositions:

31 + 31606297 = 31606328
67 + 31606261 = 31606328
241 + 31606087 = 31606328
277 + 31606051 = 31606328
547 + 31605781 = 31606328
571 + 31605757 = 31606328
601 + 31605727 = 31606328
631 + 31605697 = 31606328

Showing the first eight; more decompositions exist.
