Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20796, here are decompositions:
- 7 + 20789 = 20796
- 23 + 20773 = 20796
- 37 + 20759 = 20796
- 43 + 20753 = 20796
- 47 + 20749 = 20796
- 53 + 20743 = 20796
- 79 + 20717 = 20796
- 89 + 20707 = 20796
Showing the first eight; more decompositions exist.
