Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563934, here are decompositions:

5 + 31563929 = 31563934
23 + 31563911 = 31563934
53 + 31563881 = 31563934
71 + 31563863 = 31563934
107 + 31563827 = 31563934
197 + 31563737 = 31563934
251 + 31563683 = 31563934
263 + 31563671 = 31563934

Showing the first eight; more decompositions exist.
