Haven't you mistaken 304 for 200 ? the 200 means that the server is sending
the whole content to the client, while 304 means server is telling the
client that the content on client is still fresh. So with big expire time
you could expect much of 304's and little of 200's.

Note that the client's cache can be also purged, objects in it can expire
because of cache size.
