Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18256, here are decompositions:
- 3 + 18253 = 18256
- 5 + 18251 = 18256
- 23 + 18233 = 18256
- 107 + 18149 = 18256
- 113 + 18143 = 18256
- 137 + 18119 = 18256
- 167 + 18089 = 18256
- 179 + 18077 = 18256
Showing the first eight; more decompositions exist.
