Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608008, here are decompositions:

37 + 31607971 = 31608008
139 + 31607869 = 31608008
151 + 31607857 = 31608008
337 + 31607671 = 31608008
379 + 31607629 = 31608008
409 + 31607599 = 31608008
457 + 31607551 = 31608008
547 + 31607461 = 31608008

Showing the first eight; more decompositions exist.
