Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90686, here are decompositions:
- 7 + 90679 = 90686
- 67 + 90619 = 90686
- 103 + 90583 = 90686
- 139 + 90547 = 90686
- 157 + 90529 = 90686
- 163 + 90523 = 90686
- 283 + 90403 = 90686
- 307 + 90379 = 90686
Showing the first eight; more decompositions exist.
