Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608064, here are decompositions:

3 + 31608061 = 31608064
17 + 31608047 = 31608064
23 + 31608041 = 31608064
167 + 31607897 = 31608064
197 + 31607867 = 31608064
233 + 31607831 = 31608064
281 + 31607783 = 31608064
317 + 31607747 = 31608064

Showing the first eight; more decompositions exist.
