Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3876, here are decompositions:

13 + 3863 = 3876
23 + 3853 = 3876
29 + 3847 = 3876
43 + 3833 = 3876
53 + 3823 = 3876
73 + 3803 = 3876
79 + 3797 = 3876
83 + 3793 = 3876

Showing the first eight; more decompositions exist.
