Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607110, here are decompositions:

23 + 31607087 = 31607110
71 + 31607039 = 31607110
113 + 31606997 = 31607110
131 + 31606979 = 31607110
137 + 31606973 = 31607110
167 + 31606943 = 31607110
179 + 31606931 = 31607110
191 + 31606919 = 31607110

Showing the first eight; more decompositions exist.
