Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563324, here are decompositions:

41 + 31563283 = 31563324
47 + 31563277 = 31563324
71 + 31563253 = 31563324
103 + 31563221 = 31563324
131 + 31563193 = 31563324
137 + 31563187 = 31563324
193 + 31563131 = 31563324
197 + 31563127 = 31563324

Showing the first eight; more decompositions exist.
