Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23842, here are decompositions:
- 11 + 23831 = 23842
- 23 + 23819 = 23842
- 29 + 23813 = 23842
- 41 + 23801 = 23842
- 53 + 23789 = 23842
- 89 + 23753 = 23842
- 101 + 23741 = 23842
- 173 + 23669 = 23842
Showing the first eight; more decompositions exist.
