Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3810, here are decompositions:

7 + 3803 = 3810
13 + 3797 = 3810
17 + 3793 = 3810
31 + 3779 = 3810
41 + 3769 = 3810
43 + 3767 = 3810
71 + 3739 = 3810
83 + 3727 = 3810

Showing the first eight; more decompositions exist.
