Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18366, here are decompositions:

13 + 18353 = 18366
37 + 18329 = 18366
53 + 18313 = 18366
59 + 18307 = 18366
79 + 18287 = 18366
97 + 18269 = 18366
109 + 18257 = 18366
113 + 18253 = 18366

Showing the first eight; more decompositions exist.
