Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3880, here are decompositions:

3 + 3877 = 3880
17 + 3863 = 3880
29 + 3851 = 3880
47 + 3833 = 3880
59 + 3821 = 3880
83 + 3797 = 3880
101 + 3779 = 3880
113 + 3767 = 3880

Showing the first eight; more decompositions exist.
