Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18340, here are decompositions:

11 + 18329 = 18340
29 + 18311 = 18340
53 + 18287 = 18340
71 + 18269 = 18340
83 + 18257 = 18340
89 + 18251 = 18340
107 + 18233 = 18340
149 + 18191 = 18340

Showing the first eight; more decompositions exist.
