Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12832, here are decompositions:
- 3 + 12829 = 12832
- 11 + 12821 = 12832
- 23 + 12809 = 12832
- 41 + 12791 = 12832
- 89 + 12743 = 12832
- 173 + 12659 = 12832
- 179 + 12653 = 12832
- 191 + 12641 = 12832
Showing the first eight; more decompositions exist.
