You could do this with Solver but with 3000 number, it is unlikely that
there is a unique solution.
Do you care?

I have a list of numbers (approximately 3000) that sum to X. However, my
control figure is Y.

Is there a formula that will evaluate the list of 3000 numbers and return
those that when summed, equal the difference between X and Y?
