Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3018, here are decompositions:

7 + 3011 = 3018
17 + 3001 = 3018
19 + 2999 = 3018
47 + 2971 = 3018
61 + 2957 = 3018
79 + 2939 = 3018
101 + 2917 = 3018
109 + 2909 = 3018

Showing the first eight; more decompositions exist.
