Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563922, here are decompositions:

11 + 31563911 = 31563922
23 + 31563899 = 31563922
41 + 31563881 = 31563922
59 + 31563863 = 31563922
149 + 31563773 = 31563922
239 + 31563683 = 31563922
251 + 31563671 = 31563922
353 + 31563569 = 31563922

Showing the first eight; more decompositions exist.
