Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20764, here are decompositions:
- 5 + 20759 = 20764
- 11 + 20753 = 20764
- 17 + 20747 = 20764
- 47 + 20717 = 20764
- 71 + 20693 = 20764
- 83 + 20681 = 20764
- 101 + 20663 = 20764
- 137 + 20627 = 20764
Showing the first eight; more decompositions exist.
