Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12836, here are decompositions:
- 7 + 12829 = 12836
- 13 + 12823 = 12836
- 37 + 12799 = 12836
- 73 + 12763 = 12836
- 79 + 12757 = 12836
- 97 + 12739 = 12836
- 139 + 12697 = 12836
- 199 + 12637 = 12836
Showing the first eight; more decompositions exist.
