You can't. There is no way to go from an 04t package version Id to the package's namespace and version number. In fact, it may not have a unique namespace and version number that identify the package: if this is a 2GP version, there may exist multiple packages with distinct 04t ids but the same namespace and version number.

If you need to install a package using an 04t id, use the Tooling API's PackageInstallRequest object instead of the Metadata API.
