Then something like YVR-IAD (perhaps via ORD) and on to LON (UA dropped JFK-LHR late last year), before picking up EK again. TYO is out of your itinerary as you would be backtracking. An ALT would be

EBB-DXB-BKK (stop) - your own paid or mileage sidetrip to Oz - then BKK-TYO on UA, TYO-SFO-YVR-NYC-IAD-LHR on UA, then LHR-DXB with EK. Cheaper fare as it is North Pacific RTW.

Hope this helps.
