Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3888, here are decompositions:

7 + 3881 = 3888
11 + 3877 = 3888
37 + 3851 = 3888
41 + 3847 = 3888
67 + 3821 = 3888
109 + 3779 = 3888
127 + 3761 = 3888
149 + 3739 = 3888

Showing the first eight; more decompositions exist.
