Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563234, here are decompositions:

13 + 31563221 = 31563234
41 + 31563193 = 31563234
47 + 31563187 = 31563234
71 + 31563163 = 31563234
97 + 31563137 = 31563234
103 + 31563131 = 31563234
107 + 31563127 = 31563234
191 + 31563043 = 31563234

Showing the first eight; more decompositions exist.
