Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559652, here are decompositions:

11 + 31559641 = 31559652
13 + 31559639 = 31559652
29 + 31559623 = 31559652
79 + 31559573 = 31559652
151 + 31559501 = 31559652
181 + 31559471 = 31559652
239 + 31559413 = 31559652
251 + 31559401 = 31559652

Showing the first eight; more decompositions exist.
