Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563264, here are decompositions:

11 + 31563253 = 31563264
43 + 31563221 = 31563264
71 + 31563193 = 31563264
101 + 31563163 = 31563264
127 + 31563137 = 31563264
137 + 31563127 = 31563264
191 + 31563073 = 31563264
223 + 31563041 = 31563264

Showing the first eight; more decompositions exist.
