Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78736, here are decompositions:
- 23 + 78713 = 78736
- 29 + 78707 = 78736
- 83 + 78653 = 78736
- 113 + 78623 = 78736
- 167 + 78569 = 78736
- 197 + 78539 = 78736
- 227 + 78509 = 78736
- 239 + 78497 = 78736
Showing the first eight; more decompositions exist.
