I don't really understand your question (it's getting late), but don't forget that momentum is a VECTOR! It has direction. By 'adjusting' the angle at which the two photons are emitted, you can increase or decrease the net momentum. Two photons moving in the same direction don't have the same momentum as two photons moving away from each other (those would have a net momentum of zero).
