Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563606, here are decompositions:

5 + 31563601 = 31563606
13 + 31563593 = 31563606
37 + 31563569 = 31563606
79 + 31563527 = 31563606
163 + 31563443 = 31563606
229 + 31563377 = 31563606
257 + 31563349 = 31563606
337 + 31563269 = 31563606

Showing the first eight; more decompositions exist.
