To the outside earth`s core is 4600 miles

The radial thickness of the inner and outer core is equal to 3,486 km (2,166 miles). The mantle is 2,885 km (1,793 miles) thick. As such the inner and outer core combined is 601 km (373 miles) thicker than the mantle.

I'm not sure what exactly you're asking, but the distance from the Earth's surface at the equator, through the two cores (the outer core and the inner core), to the center of the Earth is approximately 3963 miles.
about 5,115 km The Outer Core spans from 2,890-5,150 KM (1,790-3,160 Miles) down from sea level. The Inner Core spams from 5,150-6,360 KM (3,160-3,954 Miles) down from sea level.
The border between the inner core and the outer core is approximately 5,150 kilometers below the Earth's surface.
REALLY REALLY FAR (I wouldn't try it)
5 to 25 miles thick
The border between the inner and outer core beneath the Earth's crust is roughly 1,800 miles deep.
The distance from the boundary between the mantle and the outer core, to the center of the Earth, is around 3,470 km, or 2,156 miles.
