Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607266, here are decompositions:

3 + 31607263 = 31607266
29 + 31607237 = 31607266
59 + 31607207 = 31607266
113 + 31607153 = 31607266
179 + 31607087 = 31607266
227 + 31607039 = 31607266
269 + 31606997 = 31607266
293 + 31606973 = 31607266

Showing the first eight; more decompositions exist.
