Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40724, here are decompositions:
- 31 + 40693 = 40724
- 97 + 40627 = 40724
- 127 + 40597 = 40724
- 181 + 40543 = 40724
- 193 + 40531 = 40724
- 241 + 40483 = 40724
- 337 + 40387 = 40724
- 367 + 40357 = 40724
Showing the first eight; more decompositions exist.
