Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608364, here are decompositions:

23 + 31608341 = 31608364
101 + 31608263 = 31608364
197 + 31608167 = 31608364
233 + 31608131 = 31608364
257 + 31608107 = 31608364
317 + 31608047 = 31608364
443 + 31607921 = 31608364
461 + 31607903 = 31608364

Showing the first eight; more decompositions exist.
