Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668042, here are decompositions:
- 11 + 8668031 = 8668042
- 41 + 8668001 = 8668042
- 113 + 8667929 = 8668042
- 179 + 8667863 = 8668042
- 233 + 8667809 = 8668042
- 353 + 8667689 = 8668042
- 389 + 8667653 = 8668042
- 401 + 8667641 = 8668042
Showing the first eight; more decompositions exist.
