Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563964, here are decompositions:

11 + 31563953 = 31563964
17 + 31563947 = 31563964
23 + 31563941 = 31563964
53 + 31563911 = 31563964
83 + 31563881 = 31563964
101 + 31563863 = 31563964
137 + 31563827 = 31563964
191 + 31563773 = 31563964

Showing the first eight; more decompositions exist.
