Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90812, here are decompositions:
- 19 + 90793 = 90812
- 103 + 90709 = 90812
- 109 + 90703 = 90812
- 181 + 90631 = 90812
- 193 + 90619 = 90812
- 229 + 90583 = 90812
- 283 + 90529 = 90812
- 313 + 90499 = 90812
Showing the first eight; more decompositions exist.
