Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 170838, here are decompositions:
- 11 + 170827 = 170838
- 29 + 170809 = 170838
- 37 + 170801 = 170838
- 61 + 170777 = 170838
- 71 + 170767 = 170838
- 79 + 170759 = 170838
- 89 + 170749 = 170838
- 97 + 170741 = 170838
Showing the first eight; more decompositions exist.
