Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3904, here are decompositions:

23 + 3881 = 3904
41 + 3863 = 3904
53 + 3851 = 3904
71 + 3833 = 3904
83 + 3821 = 3904
101 + 3803 = 3904
107 + 3797 = 3904
137 + 3767 = 3904

Showing the first eight; more decompositions exist.
