Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18266, here are decompositions:

13 + 18253 = 18266
37 + 18229 = 18266
43 + 18223 = 18266
67 + 18199 = 18266
97 + 18169 = 18266
139 + 18127 = 18266
223 + 18043 = 18266
277 + 17989 = 18266

Showing the first eight; more decompositions exist.
