Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18286, here are decompositions:

17 + 18269 = 18286
29 + 18257 = 18286
53 + 18233 = 18286
137 + 18149 = 18286
167 + 18119 = 18286
197 + 18089 = 18286
227 + 18059 = 18286
239 + 18047 = 18286

Showing the first eight; more decompositions exist.
