Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6842, here are decompositions:
- 13 + 6829 = 6842
- 19 + 6823 = 6842
- 61 + 6781 = 6842
- 79 + 6763 = 6842
- 109 + 6733 = 6842
- 139 + 6703 = 6842
- 151 + 6691 = 6842
- 163 + 6679 = 6842
Showing the first eight; more decompositions exist.
