Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531924, here are decompositions:

5 + 531919 = 531924
13 + 531911 = 531924
23 + 531901 = 531924
47 + 531877 = 531924
53 + 531871 = 531924
61 + 531863 = 531924
67 + 531857 = 531924
83 + 531841 = 531924

Showing the first eight; more decompositions exist.
