Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3808, here are decompositions:

5 + 3803 = 3808
11 + 3797 = 3808
29 + 3779 = 3808
41 + 3767 = 3808
47 + 3761 = 3808
89 + 3719 = 3808
107 + 3701 = 3808
131 + 3677 = 3808

Showing the first eight; more decompositions exist.
