Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607080, here are decompositions:

41 + 31607039 = 31607080
83 + 31606997 = 31607080
101 + 31606979 = 31607080
107 + 31606973 = 31607080
137 + 31606943 = 31607080
149 + 31606931 = 31607080
233 + 31606847 = 31607080
251 + 31606829 = 31607080

Showing the first eight; more decompositions exist.
