Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18298, here are decompositions:

11 + 18287 = 18298
29 + 18269 = 18298
41 + 18257 = 18298
47 + 18251 = 18298
107 + 18191 = 18298
149 + 18149 = 18298
167 + 18131 = 18298
179 + 18119 = 18298

Showing the first eight; more decompositions exist.
