Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3846, here are decompositions:

13 + 3833 = 3846
23 + 3823 = 3846
43 + 3803 = 3846
53 + 3793 = 3846
67 + 3779 = 3846
79 + 3767 = 3846
107 + 3739 = 3846
113 + 3733 = 3846

Showing the first eight; more decompositions exist.
