Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606008, here are decompositions:

37 + 31605971 = 31606008
79 + 31605929 = 31606008
131 + 31605877 = 31606008
197 + 31605811 = 31606008
199 + 31605809 = 31606008
227 + 31605781 = 31606008
229 + 31605779 = 31606008
251 + 31605757 = 31606008

Showing the first eight; more decompositions exist.
