I would like to commend you, AP4, on your use of the word 'wowzers'. Not only for the bravery involved, but also the challenging spelling dilemma,
and the great comedy value. Thank you.
Anyway, I think the above maths is just coincidence and/or another way of getting to the 8754 clue. Oh, and:
8754+2163=10917
8754-2163=6591
....
10917-6591=4326

4326 is, by default, 2 x 2163, due to the way you worked it out.
