Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45730, here are decompositions:
- 23 + 45707 = 45730
- 53 + 45677 = 45730
- 71 + 45659 = 45730
- 89 + 45641 = 45730
- 131 + 45599 = 45730
- 173 + 45557 = 45730
- 197 + 45533 = 45730
- 227 + 45503 = 45730
Showing the first eight; more decompositions exist.
