Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531606, here are decompositions:

83 + 31531523 = 31531606
149 + 31531457 = 31531606
389 + 31531217 = 31531606
443 + 31531163 = 31531606
467 + 31531139 = 31531606
647 + 31530959 = 31531606
773 + 31530833 = 31531606
809 + 31530797 = 31531606

Showing the first eight; more decompositions exist.
