Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3908, here are decompositions:

19 + 3889 = 3908
31 + 3877 = 3908
61 + 3847 = 3908
139 + 3769 = 3908
181 + 3727 = 3908
199 + 3709 = 3908
211 + 3697 = 3908
271 + 3637 = 3908

Showing the first eight; more decompositions exist.
