Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3812, here are decompositions:

19 + 3793 = 3812
43 + 3769 = 3812
73 + 3739 = 3812
79 + 3733 = 3812
103 + 3709 = 3812
139 + 3673 = 3812
181 + 3631 = 3812
199 + 3613 = 3812

Showing the first eight; more decompositions exist.
