Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45742, here are decompositions:
- 5 + 45737 = 45742
- 83 + 45659 = 45742
- 101 + 45641 = 45742
- 173 + 45569 = 45742
- 239 + 45503 = 45742
- 251 + 45491 = 45742
- 353 + 45389 = 45742
- 401 + 45341 = 45742
Showing the first eight; more decompositions exist.
