Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608324, here are decompositions:

5 + 31608319 = 31608324
23 + 31608301 = 31608324
53 + 31608271 = 31608324
61 + 31608263 = 31608324
107 + 31608217 = 31608324
157 + 31608167 = 31608324
191 + 31608133 = 31608324
193 + 31608131 = 31608324

Showing the first eight; more decompositions exist.
