Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539604, here are decompositions:

11 + 31539593 = 31539604
17 + 31539587 = 31539604
137 + 31539467 = 31539604
191 + 31539413 = 31539604
227 + 31539377 = 31539604
251 + 31539353 = 31539604
461 + 31539143 = 31539604
521 + 31539083 = 31539604

Showing the first eight; more decompositions exist.
