Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20496, here are decompositions:
- 13 + 20483 = 20496
- 17 + 20479 = 20496
- 19 + 20477 = 20496
- 53 + 20443 = 20496
- 89 + 20407 = 20496
- 97 + 20399 = 20496
- 103 + 20393 = 20496
- 107 + 20389 = 20496
Showing the first eight; more decompositions exist.
