Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563954, here are decompositions:

5 + 31563949 = 31563954
7 + 31563947 = 31563954
11 + 31563943 = 31563954
13 + 31563941 = 31563954
17 + 31563937 = 31563954
43 + 31563911 = 31563954
47 + 31563907 = 31563954
73 + 31563881 = 31563954

Showing the first eight; more decompositions exist.
