Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608968, here are decompositions:

31 + 31608937 = 31608968
151 + 31608817 = 31608968
211 + 31608757 = 31608968
241 + 31608727 = 31608968
271 + 31608697 = 31608968
379 + 31608589 = 31608968
439 + 31608529 = 31608968
487 + 31608481 = 31608968

Showing the first eight; more decompositions exist.
