Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26806, here are decompositions:
- 5 + 26801 = 26806
- 23 + 26783 = 26806
- 29 + 26777 = 26806
- 47 + 26759 = 26806
- 83 + 26723 = 26806
- 89 + 26717 = 26806
- 107 + 26699 = 26806
- 113 + 26693 = 26806
Showing the first eight; more decompositions exist.
