Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23640, here are decompositions:
- 7 + 23633 = 23640
- 11 + 23629 = 23640
- 13 + 23627 = 23640
- 17 + 23623 = 23640
- 31 + 23609 = 23640
- 37 + 23603 = 23640
- 41 + 23599 = 23640
- 47 + 23593 = 23640
Showing the first eight; more decompositions exist.
