Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20832, here are decompositions:
- 23 + 20809 = 20832
- 43 + 20789 = 20832
- 59 + 20773 = 20832
- 61 + 20771 = 20832
- 73 + 20759 = 20832
- 79 + 20753 = 20832
- 83 + 20749 = 20832
- 89 + 20743 = 20832
Showing the first eight; more decompositions exist.
