(Maybe I'll write a factorization utility for numbers of unlimited size if I get the urge and the time. I would not take long to write. The run time could be a bit long though depending on the size of the number)

You copied that one over wrong.
30 070344 641589 375757 794798 042513 022036 007233 278736 991153 711908 276353 498617* (Composite)
You then ran:
3 007034 464158 937575 779479 804251 302203 600723 327873 699115 371190 876353 498617

You left out a '2' in the second to last 6-digit grouping.

Looks like I'm going to have to write that divisor calculator.
