Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3834, here are decompositions:

11 + 3823 = 3834
13 + 3821 = 3834
31 + 3803 = 3834
37 + 3797 = 3834
41 + 3793 = 3834
67 + 3767 = 3834
73 + 3761 = 3834
101 + 3733 = 3834

Showing the first eight; more decompositions exist.
