Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18108, here are decompositions:

11 + 18097 = 18108
19 + 18089 = 18108
31 + 18077 = 18108
47 + 18061 = 18108
59 + 18049 = 18108
61 + 18047 = 18108
67 + 18041 = 18108
127 + 17981 = 18108

Showing the first eight; more decompositions exist.
