Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4068, here are decompositions:

11 + 4057 = 4068
17 + 4051 = 4068
19 + 4049 = 4068
41 + 4027 = 4068
47 + 4021 = 4068
61 + 4007 = 4068
67 + 4001 = 4068
79 + 3989 = 4068

Showing the first eight; more decompositions exist.
