Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90668, here are decompositions:
- 37 + 90631 = 90668
- 139 + 90529 = 90668
- 157 + 90511 = 90668
- 199 + 90469 = 90668
- 229 + 90439 = 90668
- 271 + 90397 = 90668
- 379 + 90289 = 90668
- 397 + 90271 = 90668
Showing the first eight; more decompositions exist.
