Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4066, here are decompositions:

17 + 4049 = 4066
47 + 4019 = 4066
53 + 4013 = 4066
59 + 4007 = 4066
137 + 3929 = 4066
149 + 3917 = 4066
233 + 3833 = 4066
263 + 3803 = 4066

Showing the first eight; more decompositions exist.
