Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3930, here are decompositions:

7 + 3923 = 3930
11 + 3919 = 3930
13 + 3917 = 3930
19 + 3911 = 3930
23 + 3907 = 3930
41 + 3889 = 3930
53 + 3877 = 3930
67 + 3863 = 3930

Showing the first eight; more decompositions exist.
