I reached x=24,000 and found 6 new PRPs:
610^23017+23017^610, 64110 digits,
595^23148+23148^595, 64225 digits,
611^23586+23586^611, 65712 digits,
467^23596+23596^467, 62986 digits,
572^23601+23601^572, 65078 digits,
500^23793+23793^500, 64217 digits.

Index has reached #1179 L(17691,1508). I'm diverting my fastest processors to another long-term project. The gaps on which I will still be working are up a bit from the current index high so I don't see myself contributing another index update anytime soon.

Updated the page (I hope correctly): http://www.primefan.ru/xyyxf/primes.html#0

The range from 13001 to 15000 is now available for decimal length >= 56230 digits, i.e. most of the work here is already done :)

The (x,y) pairs and their decimal digit lengths are correct, as are the contributions attributed to me.

Thanks for the check :)
