Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12018, here are decompositions:

7 + 12011 = 12018
11 + 12007 = 12018
31 + 11987 = 12018
37 + 11981 = 12018
47 + 11971 = 12018
59 + 11959 = 12018
79 + 11939 = 12018
109 + 11909 = 12018

Showing the first eight; more decompositions exist.
