Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613008, here are decompositions:

17 + 31612991 = 31613008
47 + 31612961 = 31613008
269 + 31612739 = 31613008
281 + 31612727 = 31613008
347 + 31612661 = 31613008
389 + 31612619 = 31613008
419 + 31612589 = 31613008
461 + 31612547 = 31613008

Showing the first eight; more decompositions exist.
