Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90666, here are decompositions:
- 7 + 90659 = 90666
- 19 + 90647 = 90666
- 47 + 90619 = 90666
- 67 + 90599 = 90666
- 83 + 90583 = 90666
- 137 + 90529 = 90666
- 139 + 90527 = 90666
- 167 + 90499 = 90666
Showing the first eight; more decompositions exist.
