There are 21 two-digit prime numbers.

7 two-digit numbers.

73 is the largest two-digit number that is prime and has prime numbers for both of its digits.

679 is the product of the largest single-digit prime number and the largest two-digit prime number.

There are only two prime numbers that are consecutive numbers, 2 and 3. Their product is 2 x 3 = 6. The first prime numbers are 2, 3, 5, and 7 and the only two consecutive prime numbers whose product is a single digit are 2 and 3. (The next two consecutive prime numbers, 3 and 5, have a two-digit product.)

The first five two-digit prime numbers are 11, 13, 17, 19, and 23.

For a 2-digit prime number (which are all odd) to be the sum of two prime numbers, one of the prime numbers will have to be 2. That means the difference between the sum and the other addend will have to be 2. Prime numbers that differ by 2 are called twin primes. There are six pairs of 2-digit twin primes. Your numbers are 13, 19, 31, 43, 61 and 73.

23 and 29

The same as the number of two-digit numbers, since the last two digits must the same as the first two, only reversed. So I'll say there are 100 four-digit palindromes.

The answer is vague but correct . Take any two prime numbers whose combined digit length is 501 and their product will generate a 500 or a 501 digit number.
