Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607106, here are decompositions:

5 + 31607101 = 31607106
19 + 31607087 = 31607106
59 + 31607047 = 31607106
67 + 31607039 = 31607106
109 + 31606997 = 31607106
127 + 31606979 = 31607106
149 + 31606957 = 31607106
163 + 31606943 = 31607106

Showing the first eight; more decompositions exist.
