Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624984, here are decompositions:

5 + 31624979 = 31624984
311 + 31624673 = 31624984
353 + 31624631 = 31624984
617 + 31624367 = 31624984
641 + 31624343 = 31624984
647 + 31624337 = 31624984
653 + 31624331 = 31624984
701 + 31624283 = 31624984

Showing the first eight; more decompositions exist.
