Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3942, here are decompositions:

11 + 3931 = 3942
13 + 3929 = 3942
19 + 3923 = 3942
23 + 3919 = 3942
31 + 3911 = 3942
53 + 3889 = 3942
61 + 3881 = 3942
79 + 3863 = 3942

Showing the first eight; more decompositions exist.
