Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3824, here are decompositions:

3 + 3821 = 3824
31 + 3793 = 3824
97 + 3727 = 3824
127 + 3697 = 3824
151 + 3673 = 3824
181 + 3643 = 3824
193 + 3631 = 3824
211 + 3613 = 3824

Showing the first eight; more decompositions exist.
