Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18340, here are decompositions:
- 11 + 18329 = 18340
- 29 + 18311 = 18340
- 53 + 18287 = 18340
- 71 + 18269 = 18340
- 83 + 18257 = 18340
- 89 + 18251 = 18340
- 107 + 18233 = 18340
- 149 + 18191 = 18340
Showing the first eight; more decompositions exist.
