Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607330, here are decompositions:

3 + 31607327 = 31607330
31 + 31607299 = 31607330
37 + 31607293 = 31607330
67 + 31607263 = 31607330
103 + 31607227 = 31607330
193 + 31607137 = 31607330
229 + 31607101 = 31607330
283 + 31607047 = 31607330

Showing the first eight; more decompositions exist.
