"is that it?"
It is, yes.

"The other numbers are irrelevant"
They are indeed.

"I have been overthinking it"
So it would seem, yes.

(17 + 5) = 22 +(19 - 17) = 24
(13 + 3) = 16 + (17 -13) = 20
(11 +7) = 18 + (13 -11) = 20

But because West andSouth are identical in all cases, Jim's solution works also and there is no need to use all the numbers!

The total of the outside numbers increase by 2 reading left to right. Meantime the central number reduces by 4.

Do I win?!!

"Meantime the central number reduces by 4."

That's an equally valid answer!
