Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77986, here are decompositions:
- 3 + 77983 = 77986
- 17 + 77969 = 77986
- 53 + 77933 = 77986
- 137 + 77849 = 77986
- 173 + 77813 = 77986
- 239 + 77747 = 77986
- 263 + 77723 = 77986
- 443 + 77543 = 77986
Showing the first eight; more decompositions exist.
