Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608908, here are decompositions:

151 + 31608757 = 31608908
181 + 31608727 = 31608908
211 + 31608697 = 31608908
241 + 31608667 = 31608908
379 + 31608529 = 31608908
571 + 31608337 = 31608908
607 + 31608301 = 31608908
691 + 31608217 = 31608908

Showing the first eight; more decompositions exist.
