prime number question

Sort:
enemyofphilip

it's my birthdy (yes, really) and I'm 47 Cry.  obviously it's a prime but 4+7 is also prime and the digits of that prime(1 and 1) also add up to a prime. When will my next birthday have such properties?

enemyofphilip

ps and is there a name for this sort of number?
