Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18310, here are decompositions:

3 + 18307 = 18310
23 + 18287 = 18310
41 + 18269 = 18310
53 + 18257 = 18310
59 + 18251 = 18310
167 + 18143 = 18310
179 + 18131 = 18310
191 + 18119 = 18310

Showing the first eight; more decompositions exist.
