Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20466, here are decompositions:
- 23 + 20443 = 20466
- 59 + 20407 = 20466
- 67 + 20399 = 20466
- 73 + 20393 = 20466
- 97 + 20369 = 20466
- 107 + 20359 = 20466
- 109 + 20357 = 20466
- 113 + 20353 = 20466
Showing the first eight; more decompositions exist.
