Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20446, here are decompositions:
- 3 + 20443 = 20446
- 5 + 20441 = 20446
- 47 + 20399 = 20446
- 53 + 20393 = 20446
- 89 + 20357 = 20446
- 113 + 20333 = 20446
- 149 + 20297 = 20446
- 197 + 20249 = 20446
Showing the first eight; more decompositions exist.
