Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86986, here are decompositions:
- 5 + 86981 = 86986
- 17 + 86969 = 86986
- 47 + 86939 = 86986
- 59 + 86927 = 86986
- 149 + 86837 = 86986
- 173 + 86813 = 86986
- 233 + 86753 = 86986
- 257 + 86729 = 86986
Showing the first eight; more decompositions exist.
