Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613316, here are decompositions:

67 + 31613249 = 31613316
73 + 31613243 = 31613316
89 + 31613227 = 31613316
173 + 31613143 = 31613316
179 + 31613137 = 31613316
197 + 31613119 = 31613316
199 + 31613117 = 31613316
263 + 31613053 = 31613316

Showing the first eight; more decompositions exist.
