This solution considers primes greater than the number. Oh -- and "sum factors" should be "count factors".
Again, I did not build an app. I will go do it, but I will not show it here. This flow logic remains intact, even with an app.
Fun challenge. First time I've used iterative macros within macros. Also, within the iterative macro there was a macro. Certainly not the cleanest, strung together method. But it was great fun whilst learning macros. If a number has primes of equal distance above and below it. It will find both.
I went a different route. This is my first iterative Macro :)
