Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608366, here are decompositions:

17 + 31608349 = 31608366
29 + 31608337 = 31608366
47 + 31608319 = 31608366
103 + 31608263 = 31608366
149 + 31608217 = 31608366
197 + 31608169 = 31608366
199 + 31608167 = 31608366
233 + 31608133 = 31608366

Showing the first eight; more decompositions exist.
