Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20746, here are decompositions:
- 3 + 20743 = 20746
- 29 + 20717 = 20746
- 53 + 20693 = 20746
- 83 + 20663 = 20746
- 107 + 20639 = 20746
- 197 + 20549 = 20746
- 239 + 20507 = 20746
- 263 + 20483 = 20746
Showing the first eight; more decompositions exist.
