Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 56640, here are decompositions:
- 7 + 56633 = 56640
- 11 + 56629 = 56640
- 29 + 56611 = 56640
- 41 + 56599 = 56640
- 43 + 56597 = 56640
- 71 + 56569 = 56640
- 97 + 56543 = 56640
- 107 + 56533 = 56640
Showing the first eight; more decompositions exist.
