Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678218, here are decompositions:
- 5 + 8678213 = 8678218
- 71 + 8678147 = 8678218
- 89 + 8678129 = 8678218
- 137 + 8678081 = 8678218
- 149 + 8678069 = 8678218
- 167 + 8678051 = 8678218
- 179 + 8678039 = 8678218
- 191 + 8678027 = 8678218
Showing the first eight; more decompositions exist.
