Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3916, here are decompositions:

5 + 3911 = 3916
53 + 3863 = 3916
83 + 3833 = 3916
113 + 3803 = 3916
137 + 3779 = 3916
149 + 3767 = 3916
197 + 3719 = 3916
239 + 3677 = 3916

Showing the first eight; more decompositions exist.
