Another very good book is Modern Computer Algebra by Joachim von zur Gathen. It goes however well beyond number representations.

Right, thanks! That's where I started - I was hoping to factor $N = a^2+r = (a-x)(a+y)$

That's what I was looking for. And $x^2-y^2=c$ would be a Pell's equation, that could not be easily solved, could it?
