Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17842, here are decompositions:
- 3 + 17839 = 17842
- 5 + 17837 = 17842
- 53 + 17789 = 17842
- 59 + 17783 = 17842
- 113 + 17729 = 17842
- 173 + 17669 = 17842
- 233 + 17609 = 17842
- 263 + 17579 = 17842
Showing the first eight; more decompositions exist.
