"Some download clients" probably have to be fixed, as 200 is
allowed response for range requests.

You may pass Range requests to backends with something like

proxy_set_header Range $http_range;
proxy_set_header If-Range $http_if_range;

and don't cache responses to these requests at all:

proxy_no_cache $http_range $http_if_range;
