The answer is vague but correct .
Take any Prime number and any other number whose combined digit length is 401 and their product will generate a 400 or a 401 digit number.
The answer is vague but correct . Take any two prime numbers whose combined digit length is 501 and their product will generate a 500 or a 501 digit number.

Yes.
Any prime numbers of about 66 or 67 digits will do.
You seek for prime numbers that are approximately 200 digits big, then multiply them. I don't know details about the algorithms, but I understand that for cryptography, instead of using an algorithm that will be guaranteed to give a prime number, an algorithm is used, instead, that has a very, very high probability of giving a prime number. Probably this is done because it is faster.
