It appears your mail was delayed 13 days.
The largest known palindromic primes are at
http://primes.utm.edu/top20/page.php?id=53
The current record is 10^180004+248797842*10^89998+1 by Harvey Dubner.

The largest known reversible primes (palindromes disallowed) are at
http://www.primepuzzles.net/puzzles/puzz_020.htm
The current record is 10^10006+941992101*10^4999+1 by me.
