Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607076, here are decompositions:

29 + 31607047 = 31607076
37 + 31607039 = 31607076
79 + 31606997 = 31607076
97 + 31606979 = 31607076
103 + 31606973 = 31607076
113 + 31606963 = 31607076
157 + 31606919 = 31607076
173 + 31606903 = 31607076

Showing the first eight; more decompositions exist.
