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.
