Primes whose digits sum to a prime

Mooky · Apr 11, 2011

Is there a name for prime numbers whose digits sum to a prime number? For example, the prime 83 gives 8+3=11, a prime. Is there anything known about these primes, e.g. are there infinitely many of them?

Thanks,
M

OEIS http://oeis.org/A046704 calls these "additive primes" and Google finds others using this name. Perhaps that is enough to start your quest.
