Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563294, here are decompositions:

11 + 31563283 = 31563294
17 + 31563277 = 31563294
41 + 31563253 = 31563294
73 + 31563221 = 31563294
101 + 31563193 = 31563294
107 + 31563187 = 31563294
131 + 31563163 = 31563294
157 + 31563137 = 31563294

Showing the first eight; more decompositions exist.
