Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18736, here are decompositions:
- 5 + 18731 = 18736
- 17 + 18719 = 18736
- 23 + 18713 = 18736
- 149 + 18587 = 18736
- 197 + 18539 = 18736
- 233 + 18503 = 18736
- 293 + 18443 = 18736
- 383 + 18353 = 18736
Showing the first eight; more decompositions exist.
