Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3964, here are decompositions:

17 + 3947 = 3964
41 + 3923 = 3964
47 + 3917 = 3964
53 + 3911 = 3964
83 + 3881 = 3964
101 + 3863 = 3964
113 + 3851 = 3964
131 + 3833 = 3964

Showing the first eight; more decompositions exist.
