Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26640, here are decompositions:
- 7 + 26633 = 26640
- 13 + 26627 = 26640
- 43 + 26597 = 26640
- 67 + 26573 = 26640
- 79 + 26561 = 26640
- 83 + 26557 = 26640
- 101 + 26539 = 26640
- 127 + 26513 = 26640
Showing the first eight; more decompositions exist.
