33845^26604+26604^33845 is 3-PRP!

I'm not sure factordb.com will PRP this for me. I noticed that Norbert's PRPTop submissions for a couple of his larger Leyland primes has a list of prime-PRPs from prime 2 to 11. Which brings me to ask why pfgw default reports only 3-PRPs. How does one get it to do other primes? Is it even necessary?
