Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68728, here are decompositions:
- 17 + 68711 = 68728
- 29 + 68699 = 68728
- 41 + 68687 = 68728
- 59 + 68669 = 68728
- 89 + 68639 = 68728
- 131 + 68597 = 68728
- 197 + 68531 = 68728
- 227 + 68501 = 68728
Showing the first eight; more decompositions exist.
