Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77656, here are decompositions:
- 83 + 77573 = 77656
- 107 + 77549 = 77656
- 113 + 77543 = 77656
- 167 + 77489 = 77656
- 179 + 77477 = 77656
- 239 + 77417 = 77656
- 317 + 77339 = 77656
- 389 + 77267 = 77656
Showing the first eight; more decompositions exist.
