Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607214, here are decompositions:

7 + 31607207 = 31607214
13 + 31607201 = 31607214
61 + 31607153 = 31607214
113 + 31607101 = 31607214
127 + 31607087 = 31607214
167 + 31607047 = 31607214
241 + 31606973 = 31607214
251 + 31606963 = 31607214

Showing the first eight; more decompositions exist.
