If you add up every digit in a primenumber and the result is a primenumber too, you’ve got a hyperprime. F.ex 313 is a prime, and 3 + 1 + 3 = 7, which is also a prime. If you reverse the digits in a primenumber and get a new prime, it’s a palindromeprime. F.ex 30529 is a prime, and 92503 is a prime.
