Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3892, here are decompositions:

3 + 3889 = 3892
11 + 3881 = 3892
29 + 3863 = 3892
41 + 3851 = 3892
59 + 3833 = 3892
71 + 3821 = 3892
89 + 3803 = 3892
113 + 3779 = 3892

Showing the first eight; more decompositions exist.
