Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16842, here are decompositions:
- 11 + 16831 = 16842
- 13 + 16829 = 16842
- 19 + 16823 = 16842
- 31 + 16811 = 16842
- 79 + 16763 = 16842
- 83 + 16759 = 16842
- 101 + 16741 = 16842
- 113 + 16729 = 16842
Showing the first eight; more decompositions exist.
