Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20724, here are decompositions:
- 5 + 20719 = 20724
- 7 + 20717 = 20724
- 17 + 20707 = 20724
- 31 + 20693 = 20724
- 43 + 20681 = 20724
- 61 + 20663 = 20724
- 83 + 20641 = 20724
- 97 + 20627 = 20724
Showing the first eight; more decompositions exist.
