Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45724, here are decompositions:
- 17 + 45707 = 45724
- 47 + 45677 = 45724
- 83 + 45641 = 45724
- 137 + 45587 = 45724
- 167 + 45557 = 45724
- 191 + 45533 = 45724
- 227 + 45497 = 45724
- 233 + 45491 = 45724
Showing the first eight; more decompositions exist.
