Convertion from EPSG:31469 to EPSG:3857 produces absolute wrong resutl

[MarcelHeckel]

The coordinate produces 5439627.33, 5661628.09 a completely wrong result when converting from EPSG:31469 to EPSG:3857 -4168119.848846665, 5803607.27843846 but should be something like: 1573655, 6636624

Sorry, I should RTFM
