Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3770, here are decompositions:

3 + 3767 = 3770
31 + 3739 = 3770
37 + 3733 = 3770
43 + 3727 = 3770
61 + 3709 = 3770
73 + 3697 = 3770
79 + 3691 = 3770
97 + 3673 = 3770

Showing the first eight; more decompositions exist.
