Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3800, here are decompositions:

3 + 3797 = 3800
7 + 3793 = 3800
31 + 3769 = 3800
61 + 3739 = 3800
67 + 3733 = 3800
73 + 3727 = 3800
103 + 3697 = 3800
109 + 3691 = 3800

Showing the first eight; more decompositions exist.
