Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3836, here are decompositions:

3 + 3833 = 3836
13 + 3823 = 3836
43 + 3793 = 3836
67 + 3769 = 3836
97 + 3739 = 3836
103 + 3733 = 3836
109 + 3727 = 3836
127 + 3709 = 3836

Showing the first eight; more decompositions exist.
