Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608322, here are decompositions:

3 + 31608319 = 31608322
59 + 31608263 = 31608322
173 + 31608149 = 31608322
191 + 31608131 = 31608322
281 + 31608041 = 31608322
293 + 31608029 = 31608322
353 + 31607969 = 31608322
401 + 31607921 = 31608322

Showing the first eight; more decompositions exist.
