Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608336, here are decompositions:

17 + 31608319 = 31608336
73 + 31608263 = 31608336
167 + 31608169 = 31608336
173 + 31608163 = 31608336
229 + 31608107 = 31608336
269 + 31608067 = 31608336
307 + 31608029 = 31608336
367 + 31607969 = 31608336

Showing the first eight; more decompositions exist.
