Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539652, here are decompositions:

3 + 31539649 = 31539652
59 + 31539593 = 31539652
83 + 31539569 = 31539652
239 + 31539413 = 31539652
251 + 31539401 = 31539652
461 + 31539191 = 31539652
509 + 31539143 = 31539652
563 + 31539089 = 31539652

Showing the first eight; more decompositions exist.
