Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608342, here are decompositions:

5 + 31608337 = 31608342
23 + 31608319 = 31608342
41 + 31608301 = 31608342
71 + 31608271 = 31608342
79 + 31608263 = 31608342
173 + 31608169 = 31608342
179 + 31608163 = 31608342
193 + 31608149 = 31608342

Showing the first eight; more decompositions exist.
