no,its not always......
for example see 23.........but it's reverse(32) isn't prime.
one is 17 and 71, another one is 11,
Mirror primes are pairs of prime numbers whose digits are reversed. (13,31)(17,71)(37,73)(79,97)
There are no other prime numbers that are even but 2.
The only even prime number is 2.
They are prime numbers when you reverse the first one, the second one is prime also.
13,31 17,71 37,73 79,97
Prime numbers that are still prime after their digits are reversed, like (13,31)(17,71)(37,73)(79,97)(107,701)(113,311)
Some of them are: 11 13 17 37 and 79
All the two digit prime numbers that can be reversed are 11, 13 and 31, 17 and 71, 37 and 73, and 79 and 97.
one is 17 and 71, another one is 11,
(13,31)(17,71)(37,73)(79,97)(107,701)(113,311)
Mirror primes are pairs of prime numbers whose digits are reversed. (13,31)(17,71)(37,73)(79,97)
11 13 17 31 37 71 73 79 97
You don't. All prime numbers are also whole numbers.
There are no other prime numbers that are even but 2.
This can be an extension to the proof that there are infinitely many prime numbers. If there are infinitely many prime numbers, then there are also infinitely many PRODUCTS of prime numbers. Those numbers that are the product of 2 or more prime numbers are not prime numbers.
The only even prime number is 2.
