Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79842, here are decompositions:
- 13 + 79829 = 79842
- 19 + 79823 = 79842
- 29 + 79813 = 79842
- 31 + 79811 = 79842
- 41 + 79801 = 79842
- 73 + 79769 = 79842
- 149 + 79693 = 79842
- 151 + 79691 = 79842
Showing the first eight; more decompositions exist.
