Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608474, here are decompositions:

47 + 31608427 = 31608474
137 + 31608337 = 31608474
173 + 31608301 = 31608474
211 + 31608263 = 31608474
257 + 31608217 = 31608474
307 + 31608167 = 31608474
311 + 31608163 = 31608474
367 + 31608107 = 31608474

Showing the first eight; more decompositions exist.
