Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171768, here are decompositions:
- 5 + 171763 = 171768
- 7 + 171761 = 171768
- 11 + 171757 = 171768
- 61 + 171707 = 171768
- 71 + 171697 = 171768
- 89 + 171679 = 171768
- 97 + 171671 = 171768
- 109 + 171659 = 171768
Showing the first eight; more decompositions exist.
