Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563682, here are decompositions:

11 + 31563671 = 31563682
89 + 31563593 = 31563682
113 + 31563569 = 31563682
131 + 31563551 = 31563682
191 + 31563491 = 31563682
239 + 31563443 = 31563682
251 + 31563431 = 31563682
281 + 31563401 = 31563682

Showing the first eight; more decompositions exist.
