Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 76800, here are decompositions:
- 19 + 76781 = 76800
- 23 + 76777 = 76800
- 29 + 76771 = 76800
- 43 + 76757 = 76800
- 47 + 76753 = 76800
- 67 + 76733 = 76800
- 83 + 76717 = 76800
- 103 + 76697 = 76800
Showing the first eight; more decompositions exist.
