Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563924, here are decompositions:

13 + 31563911 = 31563924
17 + 31563907 = 31563924
43 + 31563881 = 31563924
47 + 31563877 = 31563924
53 + 31563871 = 31563924
61 + 31563863 = 31563924
97 + 31563827 = 31563924
107 + 31563817 = 31563924

Showing the first eight; more decompositions exist.
