Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543924, here are decompositions:

11 + 31543913 = 31543924
17 + 31543907 = 31543924
47 + 31543877 = 31543924
53 + 31543871 = 31543924
107 + 31543817 = 31543924
173 + 31543751 = 31543924
227 + 31543697 = 31543924
233 + 31543691 = 31543924

Showing the first eight; more decompositions exist.
