Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668674, here are decompositions:
- 31 + 8668643 = 8668674
- 37 + 8668637 = 8668674
- 61 + 8668613 = 8668674
- 97 + 8668577 = 8668674
- 103 + 8668571 = 8668674
- 127 + 8668547 = 8668674
- 151 + 8668523 = 8668674
- 173 + 8668501 = 8668674
Showing the first eight; more decompositions exist.
