Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563952, here are decompositions:

3 + 31563949 = 31563952
5 + 31563947 = 31563952
11 + 31563941 = 31563952
23 + 31563929 = 31563952
41 + 31563911 = 31563952
53 + 31563899 = 31563952
71 + 31563881 = 31563952
89 + 31563863 = 31563952

Showing the first eight; more decompositions exist.
