Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 177656, here are decompositions:
- 67 + 177589 = 177656
- 103 + 177553 = 177656
- 163 + 177493 = 177656
- 223 + 177433 = 177656
- 229 + 177427 = 177656
- 277 + 177379 = 177656
- 337 + 177319 = 177656
- 373 + 177283 = 177656
Showing the first eight; more decompositions exist.
