Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18268, here are decompositions:
- 11 + 18257 = 18268
- 17 + 18251 = 18268
- 137 + 18131 = 18268
- 149 + 18119 = 18268
- 179 + 18089 = 18268
- 191 + 18077 = 18268
- 227 + 18041 = 18268
- 281 + 17987 = 18268
Showing the first eight; more decompositions exist.
