You can keep on using your best d, no false results should happen. If you want you can check found factors, convert each line of the .del file (using emacs for example) as follows.
Original line:
23004155641343 | 2995125705*2^932764-1
Converted to:
(2995125705*2^932764-1)%23004155641343
Then feed the converted .del file to pfgw. All results should be "Zero".
