Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3822, here are decompositions:

19 + 3803 = 3822
29 + 3793 = 3822
43 + 3779 = 3822
53 + 3769 = 3822
61 + 3761 = 3822
83 + 3739 = 3822
89 + 3733 = 3822
103 + 3719 = 3822

Showing the first eight; more decompositions exist.
