Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3906, here are decompositions:

17 + 3889 = 3906
29 + 3877 = 3906
43 + 3863 = 3906
53 + 3853 = 3906
59 + 3847 = 3906
73 + 3833 = 3906
83 + 3823 = 3906
103 + 3803 = 3906

Showing the first eight; more decompositions exist.
