Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607268, here are decompositions:

5 + 31607263 = 31607268
31 + 31607237 = 31607268
41 + 31607227 = 31607268
61 + 31607207 = 31607268
67 + 31607201 = 31607268
131 + 31607137 = 31607268
167 + 31607101 = 31607268
181 + 31607087 = 31607268

Showing the first eight; more decompositions exist.
