Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3886, here are decompositions:

5 + 3881 = 3886
23 + 3863 = 3886
53 + 3833 = 3886
83 + 3803 = 3886
89 + 3797 = 3886
107 + 3779 = 3886
167 + 3719 = 3886
227 + 3659 = 3886

Showing the first eight; more decompositions exist.
