Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668788, here are decompositions:
- 5 + 8668783 = 8668788
- 47 + 8668741 = 8668788
- 67 + 8668721 = 8668788
- 101 + 8668687 = 8668788
- 151 + 8668637 = 8668788
- 179 + 8668609 = 8668788
- 211 + 8668577 = 8668788
- 239 + 8668549 = 8668788
Showing the first eight; more decompositions exist.
