Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563316, here are decompositions:

47 + 31563269 = 31563316
107 + 31563209 = 31563316
167 + 31563149 = 31563316
179 + 31563137 = 31563316
227 + 31563089 = 31563316
467 + 31562849 = 31563316
773 + 31562543 = 31563316
797 + 31562519 = 31563316

Showing the first eight; more decompositions exist.
