Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 177666, here are decompositions:
- 19 + 177647 = 177666
- 43 + 177623 = 177666
- 113 + 177553 = 177666
- 127 + 177539 = 177666
- 173 + 177493 = 177666
- 179 + 177487 = 177666
- 193 + 177473 = 177666
- 199 + 177467 = 177666
Showing the first eight; more decompositions exist.
