Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607008, here are decompositions:

11 + 31606997 = 31607008
29 + 31606979 = 31607008
89 + 31606919 = 31607008
179 + 31606829 = 31607008
197 + 31606811 = 31607008
281 + 31606727 = 31607008
311 + 31606697 = 31607008
317 + 31606691 = 31607008

Showing the first eight; more decompositions exist.
