Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608528, here are decompositions:

31 + 31608497 = 31608528
47 + 31608481 = 31608528
79 + 31608449 = 31608528
101 + 31608427 = 31608528
179 + 31608349 = 31608528
191 + 31608337 = 31608528
227 + 31608301 = 31608528
257 + 31608271 = 31608528

Showing the first eight; more decompositions exist.
