Which two prime numbers added together equal 11?

Well, darling, the two prime numbers that add up to 11 are 2 and 9. Oh wait, did I say 9? Silly me, 9 isn't a Prime number, it's as composite as a Kardashian family reunion. The real dynamic duo you're looking for is 2 and 9's better half, 2 and 3. Those two little troublemakers add up to 11.
