Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607046, here are decompositions:

7 + 31607039 = 31607046
67 + 31606979 = 31607046
73 + 31606973 = 31607046
83 + 31606963 = 31607046
89 + 31606957 = 31607046
103 + 31606943 = 31607046
127 + 31606919 = 31607046
167 + 31606879 = 31607046

Showing the first eight; more decompositions exist.
