Quick whip up of the frame, seem about right?
Seems a bit overkill and could possibly halve the number of noggins but figure a central beam is worth it if the boards are perpendicular to frame. Actually, given the orientation of the decking boards does it make more sense to have several long joists along the length?
Edit- I know 4x2 usually measure 47mm but close enough for now.
