Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3874, here are decompositions:

11 + 3863 = 3874
23 + 3851 = 3874
41 + 3833 = 3874
53 + 3821 = 3874
71 + 3803 = 3874
107 + 3767 = 3874
113 + 3761 = 3874
173 + 3701 = 3874

Showing the first eight; more decompositions exist.
