Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18266, here are decompositions:
- 13 + 18253 = 18266
- 37 + 18229 = 18266
- 43 + 18223 = 18266
- 67 + 18199 = 18266
- 97 + 18169 = 18266
- 139 + 18127 = 18266
- 223 + 18043 = 18266
- 277 + 17989 = 18266
Showing the first eight; more decompositions exist.
