Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668800, here are decompositions:
- 17 + 8668783 = 8668800
- 37 + 8668763 = 8668800
- 59 + 8668741 = 8668800
- 61 + 8668739 = 8668800
- 79 + 8668721 = 8668800
- 89 + 8668711 = 8668800
- 103 + 8668697 = 8668800
- 113 + 8668687 = 8668800
Showing the first eight; more decompositions exist.
