Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608274, here are decompositions:

3 + 31608271 = 31608274
11 + 31608263 = 31608274
107 + 31608167 = 31608274
167 + 31608107 = 31608274
227 + 31608047 = 31608274
233 + 31608041 = 31608274
353 + 31607921 = 31608274
443 + 31607831 = 31608274

Showing the first eight; more decompositions exist.
