Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3924, here are decompositions:

5 + 3919 = 3924
7 + 3917 = 3924
13 + 3911 = 3924
17 + 3907 = 3924
43 + 3881 = 3924
47 + 3877 = 3924
61 + 3863 = 3924
71 + 3853 = 3924

Showing the first eight; more decompositions exist.
