Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608266, here are decompositions:

3 + 31608263 = 31608266
97 + 31608169 = 31608266
103 + 31608163 = 31608266
199 + 31608067 = 31608266
229 + 31608037 = 31608266
397 + 31607869 = 31608266
409 + 31607857 = 31608266
577 + 31607689 = 31608266

Showing the first eight; more decompositions exist.
