A "simple open" will require about 30GBytes of memory just to hold the
picture (do the math).  So, you will need to downsample as you open
it.  This means that you will scale it to 973 x 746 or so, reading and
storing only every 100 pixels in each direction.

I am not aware of any standard libraries that will do this.  You will
need to get one (with source) and modify it.
