Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3864, here are decompositions:

11 + 3853 = 3864
13 + 3851 = 3864
17 + 3847 = 3864
31 + 3833 = 3864
41 + 3823 = 3864
43 + 3821 = 3864
61 + 3803 = 3864
67 + 3797 = 3864

Showing the first eight; more decompositions exist.
