Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 177568, here are decompositions:
- 29 + 177539 = 177568
- 101 + 177467 = 177568
- 137 + 177431 = 177568
- 311 + 177257 = 177568
- 359 + 177209 = 177568
- 401 + 177167 = 177568
- 467 + 177101 = 177568
- 557 + 177011 = 177568
Showing the first eight; more decompositions exist.
