Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 177868, here are decompositions:
- 29 + 177839 = 177868
- 71 + 177797 = 177868
- 107 + 177761 = 177868
- 191 + 177677 = 177868
- 401 + 177467 = 177868
- 521 + 177347 = 177868
- 599 + 177269 = 177868
- 659 + 177209 = 177868
Showing the first eight; more decompositions exist.
