Dont know if this interests you, but there are three configurations available on the 767.
One has one door each side at the front, two overwings each side, and one rear door each side.
One has Two doors each side infront of the wing, and two doors each side behind the wing.
The other has one door each side at the front, one overwing each side, and two doors behind the wing each side.
The end result is that there are 4 exits each side.
These are for the 767-300 by the way.
