Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607130, here are decompositions:

29 + 31607101 = 31607130
43 + 31607087 = 31607130
83 + 31607047 = 31607130
151 + 31606979 = 31607130
157 + 31606973 = 31607130
167 + 31606963 = 31607130
173 + 31606957 = 31607130
179 + 31606951 = 31607130

Showing the first eight; more decompositions exist.
