I can verify that a sorted version of your (x,y) list matches mine and that my name appears the appropriate number of times. A sorted version of your digits list mismatched mine in one instance: The number of digits in L(12547,4354) is ten more than what you have.

Fixed that.

Thank you Hans!

I reached x=23,000 and found 2 new PRP:
677^21702+21702^677, 61430 digits,
747^22198+22198^747, 63782 digits.
