Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616008, here are decompositions:

29 + 31615979 = 31616008
89 + 31615919 = 31616008
251 + 31615757 = 31616008
419 + 31615589 = 31616008
569 + 31615439 = 31616008
617 + 31615391 = 31616008
797 + 31615211 = 31616008
821 + 31615187 = 31616008

Showing the first eight; more decompositions exist.
