Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82800, here are decompositions:
- 7 + 82793 = 82800
- 13 + 82787 = 82800
- 19 + 82781 = 82800
- 37 + 82763 = 82800
- 41 + 82759 = 82800
- 43 + 82757 = 82800
- 71 + 82729 = 82800
- 73 + 82727 = 82800
Showing the first eight; more decompositions exist.
