Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563252, here are decompositions:

31 + 31563221 = 31563252
43 + 31563209 = 31563252
59 + 31563193 = 31563252
89 + 31563163 = 31563252
103 + 31563149 = 31563252
163 + 31563089 = 31563252
179 + 31563073 = 31563252
211 + 31563041 = 31563252

Showing the first eight; more decompositions exist.
