How to convert osmium.osm.location cordinates to normal format coordinates

Question

I have extracted the coordinates data from nodes using pyosmium. Though I was successful in extracting the data but the coordinates which osmium is giving is not in normal format, I tried to convert the one of the coordinates using pyproj but the output is wrong. What is the best way to convert the pyosmium(osmium.osm.location) coordinates to normal coordinates?

The code tried:

    from pyproj import Proj, transform
    inProj = Proj(init='epsg:3857')
    outProj = Proj(init='epsg:4326')
    x2,y2 = transform(inProj,outProj,-2916285,515160418)
    print(x2,y2)
Output I got:-
(-26.197433883484983, 90.0)
