Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607068, here are decompositions:

29 + 31607039 = 31607068
71 + 31606997 = 31607068
89 + 31606979 = 31607068
137 + 31606931 = 31607068
149 + 31606919 = 31607068
239 + 31606829 = 31607068
257 + 31606811 = 31607068
401 + 31606667 = 31607068

Showing the first eight; more decompositions exist.
