Yes, but I didn't mean top5000, I meant the prime database in general. From http://primes.utm.edu/primes/search.php:

 You may also restrict the primes selected by specifying a minimum and/or maximum number of digits. Since all primes in this database have at least 1000 digits, smaller minimums would be meaningless.
So, the primes found by me can be added to the database.
There also exists http://15k.org/stats.htm -- main 15k status page, where all primes found are listed.

PS: Thanks for the formula!
