Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18366, here are decompositions:
- 13 + 18353 = 18366
- 37 + 18329 = 18366
- 53 + 18313 = 18366
- 59 + 18307 = 18366
- 79 + 18287 = 18366
- 97 + 18269 = 18366
- 109 + 18257 = 18366
- 113 + 18253 = 18366
Showing the first eight; more decompositions exist.
