Identifying Projected Coordinate System based on coordinates

I have a set of coordinates. All I know about them is that they are for locations in the US in the NAD 83 State Plane Coordinate System. Is there any way to narrow down which of the many state plane coordinate systems they might belong to short of going through each one?

Here's an example:
X: 12121117
Y: 3478079

Thanks for your thoughts.
