Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608708, here are decompositions:

11 + 31608697 = 31608708
41 + 31608667 = 31608708
179 + 31608529 = 31608708
181 + 31608527 = 31608708
211 + 31608497 = 31608708
227 + 31608481 = 31608708
281 + 31608427 = 31608708
359 + 31608349 = 31608708

Showing the first eight; more decompositions exist.
