It is impossible for the product of two prime numbers to be prime. It is impossible for the sum of two prime numbers to be prime as long as one of the numbers isn't 2.
Two is already prime. No factorization.
19 is a prime number and so there are no two prime factors.

There are no such two prime numbers, as 167 is a prime number itself.

The product of two prime numbers will be composite.

Prime numbers only have two factors, one and themselves. If you multiply two prime numbers together, the new number will also have the two prime numbers as factors, making it composite. Try it out. 5 and 7 are prime. 35 is composite.
Prime numbers have two and only two factors. If the number has more than two factors, it is not prime.
The sum of any two prime numbers may or may not be prime. The sum of the two prime numbers 2 and 3 is the prime number 5, and the sum of the two prime numbers 5 and 7 is the composite number 12.

No - because its factors include each of the two prime numbers.
