Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18376, here are decompositions:

5 + 18371 = 18376
23 + 18353 = 18376
47 + 18329 = 18376
89 + 18287 = 18376
107 + 18269 = 18376
227 + 18149 = 18376
233 + 18143 = 18376
257 + 18119 = 18376

Showing the first eight; more decompositions exist.
