Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45638, here are decompositions:
- 7 + 45631 = 45638
- 97 + 45541 = 45638
- 157 + 45481 = 45638
- 199 + 45439 = 45638
- 211 + 45427 = 45638
- 277 + 45361 = 45638
- 331 + 45307 = 45638
- 349 + 45289 = 45638
Showing the first eight; more decompositions exist.
