Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 170842, here are decompositions:
- 5 + 170837 = 170842
- 29 + 170813 = 170842
- 41 + 170801 = 170842
- 83 + 170759 = 170842
- 101 + 170741 = 170842
- 131 + 170711 = 170842
- 173 + 170669 = 170842
- 233 + 170609 = 170842
Showing the first eight; more decompositions exist.
