Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607154, here are decompositions:

17 + 31607137 = 31607154
53 + 31607101 = 31607154
67 + 31607087 = 31607154
107 + 31607047 = 31607154
157 + 31606997 = 31607154
181 + 31606973 = 31607154
191 + 31606963 = 31607154
197 + 31606957 = 31607154

Showing the first eight; more decompositions exist.
