Comment/Request

I wish to calculate the sum of 1/prime(a) with a from one to one trillion. I can calculate (with Mathematica 9 or Maple 18 ) only up to 500000, it is 3.02234. Can you calculate it, or how can I do it with your advanced online calculator? What is the one-trillionth prime or its ln? Can it handle primes? Thanks
