Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3798, here are decompositions:

5 + 3793 = 3798
19 + 3779 = 3798
29 + 3769 = 3798
31 + 3767 = 3798
37 + 3761 = 3798
59 + 3739 = 3798
71 + 3727 = 3798
79 + 3719 = 3798

Showing the first eight; more decompositions exist.
