Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19584, here are decompositions:
- 7 + 19577 = 19584
- 13 + 19571 = 19584
- 31 + 19553 = 19584
- 41 + 19543 = 19584
- 43 + 19541 = 19584
- 53 + 19531 = 19584
- 83 + 19501 = 19584
- 101 + 19483 = 19584
Showing the first eight; more decompositions exist.
