Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45808, here are decompositions:
- 29 + 45779 = 45808
- 41 + 45767 = 45808
- 71 + 45737 = 45808
- 101 + 45707 = 45808
- 131 + 45677 = 45808
- 149 + 45659 = 45808
- 167 + 45641 = 45808
- 239 + 45569 = 45808
Showing the first eight; more decompositions exist.
