Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 170646, here are decompositions:
- 5 + 170641 = 170646
- 13 + 170633 = 170646
- 19 + 170627 = 170646
- 37 + 170609 = 170646
- 43 + 170603 = 170646
- 67 + 170579 = 170646
- 89 + 170557 = 170646
- 107 + 170539 = 170646
Showing the first eight; more decompositions exist.
