Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615708, here are decompositions:

269 + 31615439 = 31615708
317 + 31615391 = 31615708
479 + 31615229 = 31615708
491 + 31615217 = 31615708
521 + 31615187 = 31615708
599 + 31615109 = 31615708
647 + 31615061 = 31615708
701 + 31615007 = 31615708

Showing the first eight; more decompositions exist.
