Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3078, here are decompositions:

11 + 3067 = 3078
17 + 3061 = 3078
29 + 3049 = 3078
37 + 3041 = 3078
41 + 3037 = 3078
59 + 3019 = 3078
67 + 3011 = 3078
79 + 2999 = 3078

Showing the first eight; more decompositions exist.
