Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18466, here are decompositions:
- 5 + 18461 = 18466
- 23 + 18443 = 18466
- 53 + 18413 = 18466
- 113 + 18353 = 18466
- 137 + 18329 = 18466
- 179 + 18287 = 18466
- 197 + 18269 = 18466
- 233 + 18233 = 18466
Showing the first eight; more decompositions exist.
