You need to also download decomp.zip and use that program:
Code:
 
How to decompress the factors and nofactors data.
1)  Download and unzip one or both of factors.zip and nofactor.zip.
2)  To get factors, run "decomp -f start_exponent end_exponent"
3)  To get the k in 2kp+1, run "decomp -k start_exponent end_exponent"
4)  To get the nofactor data, run "decomp -n start_exponent end_exponent"
5)  To get the nofactor data with "Test=" in front of each line,
    run "decomp -t start_exponent end_exponent"
6)  To get the nofactor data with "Factor=" in front of each line,
    run "decomp -w start_exponent end_exponent"
