VNC and event log

I use a variety of remote tools.
One is VNC. Im just trying to understand the event log for the vnc. Here
are the common messages.

Event Type: Information
Event Source: WinVNC4
Event Category: None
Event ID: 1
Date: 28/04/2010
Time: 4:50:29 AM
User: N/A
Computer: BACKUP
Description:
Connections: closed: 10.1.0.135::53107 (Clean disconnection)

Now the number "53107" could be and in fact is always different. I guess I
use to think that this was the Port number , but vnc commonly uses port
5800 or 5900 , which this number never is. So I'm confused what this number
is. Does anyone know?

thanks.

That's the IP and port number of the client.
