Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78986, here are decompositions:
- 7 + 78979 = 78986
- 67 + 78919 = 78986
- 97 + 78889 = 78986
- 109 + 78877 = 78986
- 163 + 78823 = 78986
- 199 + 78787 = 78986
- 337 + 78649 = 78986
- 379 + 78607 = 78986
Showing the first eight; more decompositions exist.
