Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 170860, here are decompositions:
- 3 + 170857 = 170860
- 17 + 170843 = 170860
- 23 + 170837 = 170860
- 47 + 170813 = 170860
- 59 + 170801 = 170860
- 83 + 170777 = 170860
- 101 + 170759 = 170860
- 149 + 170711 = 170860
Showing the first eight; more decompositions exist.
