I see traffic on my network to a number of unregistered TCP/UDP ports. Where
can I find a list with possible protocols that are using these ports (1535,
4889 and 8092)?

Try
http://www.google.co.uk/search?hl=en&q=udp+tcp+port+1535&meta=
http://www.google.co.uk/search?hl=en&q=udp+tcp+port+4889&meta=
http://www.google.co.uk/search?hl=en&q=udp+tcp+port+8092&meta=

The Internet Assigned Numbers Authority (IANA) is responsible for official
assignment of a TCP or UDP port to a known application. That does not mean
that any software designer could create a program to use any unregistered
TCP or UDP port that they want.
There is a Wikipedia listing for common used TCP and UDP service ports:
http://en.wikipedia.org/wiki/List_of_TCP_and_UDP_port_numbers
I did not easily find information about the three port numbers which you
listed. That leads me to believe that they are not commonly associated with
any particular application or program. Also keep in mind that only the
destination TCP or UDP port number is the relevant portion, not the source
port number.

Strictly speaking, every protocol is possible on every port. In order to
find out for sure what it is you'll have to look on the destination machine
what service is listening on the port. The picture is further complicated
by protocols that allocate ports dynamically.
Of course there are typical services for many ports. I have in the past had
good results looking up port numbers on the SANS Internet Storm Center's
"PortDetails" page at http://isc.sans.org/port.html. The ports you list,
however, didn't turn up anything interesting there.
