Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18168, here are decompositions:

19 + 18149 = 18168
37 + 18131 = 18168
41 + 18127 = 18168
47 + 18121 = 18168
71 + 18097 = 18168
79 + 18089 = 18168
107 + 18061 = 18168
109 + 18059 = 18168

Showing the first eight; more decompositions exist.
