Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8746668, here are decompositions:
- 17 + 8746651 = 8746668
- 31 + 8746637 = 8746668
- 59 + 8746609 = 8746668
- 149 + 8746519 = 8746668
- 199 + 8746469 = 8746668
- 241 + 8746427 = 8746668
- 269 + 8746399 = 8746668
- 277 + 8746391 = 8746668
Showing the first eight; more decompositions exist.
