Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20704, here are decompositions:
- 11 + 20693 = 20704
- 23 + 20681 = 20704
- 41 + 20663 = 20704
- 197 + 20507 = 20704
- 227 + 20477 = 20704
- 263 + 20441 = 20704
- 293 + 20411 = 20704
- 311 + 20393 = 20704
Showing the first eight; more decompositions exist.
