Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608068, here are decompositions:

7 + 31608061 = 31608068
31 + 31608037 = 31608068
97 + 31607971 = 31608068
199 + 31607869 = 31608068
211 + 31607857 = 31608068
229 + 31607839 = 31608068
277 + 31607791 = 31608068
379 + 31607689 = 31608068

Showing the first eight; more decompositions exist.
