Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608346, here are decompositions:

5 + 31608341 = 31608346
83 + 31608263 = 31608346
179 + 31608167 = 31608346
197 + 31608149 = 31608346
239 + 31608107 = 31608346
317 + 31608029 = 31608346
443 + 31607903 = 31608346
449 + 31607897 = 31608346

Showing the first eight; more decompositions exist.
