Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18300, here are decompositions:
- 11 + 18289 = 18300
- 13 + 18287 = 18300
- 31 + 18269 = 18300
- 43 + 18257 = 18300
- 47 + 18253 = 18300
- 67 + 18233 = 18300
- 71 + 18229 = 18300
- 83 + 18217 = 18300
Showing the first eight; more decompositions exist.
