Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83790, here are decompositions:
- 13 + 83777 = 83790
- 17 + 83773 = 83790
- 29 + 83761 = 83790
- 53 + 83737 = 83790
- 71 + 83719 = 83790
- 73 + 83717 = 83790
- 89 + 83701 = 83790
- 101 + 83689 = 83790
Showing the first eight; more decompositions exist.
