Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77686, here are decompositions:
- 5 + 77681 = 77686
- 113 + 77573 = 77686
- 137 + 77549 = 77686
- 173 + 77513 = 77686
- 197 + 77489 = 77686
- 239 + 77447 = 77686
- 269 + 77417 = 77686
- 317 + 77369 = 77686
Showing the first eight; more decompositions exist.
