The Split APK is designed for this purpose.

The initial file is supposed to be <50mb and it is intended to be a setup file for downloading the extra APK (<2GB) from the web/Play.

Check Google developer Documentation.

For an APK to install an external APK, there may be a snag.

Note that most devices come with "Allow External APKs" disabled by default so such "Sideloading" may not be permitted.
