Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607070, here are decompositions:

23 + 31607047 = 31607070
31 + 31607039 = 31607070
73 + 31606997 = 31607070
97 + 31606973 = 31607070
107 + 31606963 = 31607070
113 + 31606957 = 31607070
127 + 31606943 = 31607070
139 + 31606931 = 31607070

Showing the first eight; more decompositions exist.
