Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 170240, here are decompositions:
- 13 + 170227 = 170240
- 43 + 170197 = 170240
- 61 + 170179 = 170240
- 73 + 170167 = 170240
- 139 + 170101 = 170240
- 193 + 170047 = 170240
- 211 + 170029 = 170240
- 283 + 169957 = 170240
Showing the first eight; more decompositions exist.
