Here is a simple Python script that does what you want:
import dbus
import sys
filename=sys.argv[1]
page=sys.argv[2]
session = dbus.SessionBus()
for name in session.list_names():
if not name.startswith("org.pwmt.zathura"):
continue
proxy = session.get_object(name, "/org/pwmt/zathura")
zathura = dbus.Interface(proxy, "org.pwmt.zathura")
properties = dbus.Interface(proxy, "org.freedesktop.DBus.Properties")
ofilename = properties.Get("org.pwmt.zathura", "filename")
if ofilename != filename:
continue
zathura.GotoPage(page)
Call it with python $foo.py /absolute/path.pdf page

Maybe we should start a collection of scripts instead of putting them
all in the binary. I don't know yet.
