Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3860, here are decompositions:

7 + 3853 = 3860
13 + 3847 = 3860
37 + 3823 = 3860
67 + 3793 = 3860
127 + 3733 = 3860
151 + 3709 = 3860
163 + 3697 = 3860
223 + 3637 = 3860

Showing the first eight; more decompositions exist.
