Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668, here are decompositions:
- 5 + 8663 = 8668
- 41 + 8627 = 8668
- 59 + 8609 = 8668
- 71 + 8597 = 8668
- 131 + 8537 = 8668
- 167 + 8501 = 8668
- 239 + 8429 = 8668
- 281 + 8387 = 8668
Showing the first eight; more decompositions exist.
