Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80724, here are decompositions:
- 11 + 80713 = 80724
- 23 + 80701 = 80724
- 37 + 80687 = 80724
- 41 + 80683 = 80724
- 43 + 80681 = 80724
- 47 + 80677 = 80724
- 53 + 80671 = 80724
- 67 + 80657 = 80724
Showing the first eight; more decompositions exist.
