Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18330, here are decompositions:

17 + 18313 = 18330
19 + 18311 = 18330
23 + 18307 = 18330
29 + 18301 = 18330
41 + 18289 = 18330
43 + 18287 = 18330
61 + 18269 = 18330
73 + 18257 = 18330

Showing the first eight; more decompositions exist.
