Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20460, here are decompositions:
- 17 + 20443 = 20460
- 19 + 20441 = 20460
- 29 + 20431 = 20460
- 53 + 20407 = 20460
- 61 + 20399 = 20460
- 67 + 20393 = 20460
- 71 + 20389 = 20460
- 101 + 20359 = 20460
Showing the first eight; more decompositions exist.
