Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668684, here are decompositions:
- 41 + 8668643 = 8668684
- 47 + 8668637 = 8668684
- 71 + 8668613 = 8668684
- 107 + 8668577 = 8668684
- 113 + 8668571 = 8668684
- 131 + 8668553 = 8668684
- 137 + 8668547 = 8668684
- 263 + 8668421 = 8668684
Showing the first eight; more decompositions exist.
