Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18346, here are decompositions:

5 + 18341 = 18346
17 + 18329 = 18346
59 + 18287 = 18346
89 + 18257 = 18346
113 + 18233 = 18346
197 + 18149 = 18346
227 + 18119 = 18346
257 + 18089 = 18346

Showing the first eight; more decompositions exist.
