Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18110, here are decompositions:

13 + 18097 = 18110
61 + 18049 = 18110
67 + 18043 = 18110
97 + 18013 = 18110
139 + 17971 = 18110
151 + 17959 = 18110
181 + 17929 = 18110
199 + 17911 = 18110

Showing the first eight; more decompositions exist.
