Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3882, here are decompositions:

5 + 3877 = 3882
19 + 3863 = 3882
29 + 3853 = 3882
31 + 3851 = 3882
59 + 3823 = 3882
61 + 3821 = 3882
79 + 3803 = 3882
89 + 3793 = 3882

Showing the first eight; more decompositions exist.
