Largest known emirp

An is a prime number which is prime both forwards and backwards. The largest known emirp to date is \(10^{10,006}+{941992101\times 10^{4,999}}+1\).Prime Curios!: 10000...00001 (10007-digits)
It is an extremely easy to memorize number, as it is comprised of almost all zeroes with 1's on either side and a short number in between. The number of digits of this number is also an emirp, as both 10,007 and 70,001 are prime.
The largest known emirp is equal to about \(f_{2}(33\,224)\) in the fast-growing hierarchy.
