Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18328, here are decompositions:
- 17 + 18311 = 18328
- 41 + 18287 = 18328
- 59 + 18269 = 18328
- 71 + 18257 = 18328
- 137 + 18191 = 18328
- 179 + 18149 = 18328
- 197 + 18131 = 18328
- 239 + 18089 = 18328
Showing the first eight; more decompositions exist.
