Find a possible pair of prime numbers such that their difference is 2.
One possible pair of prime numbers such that their difference is 2 is (3, 5).
To find a possible pair of prime numbers whose difference is 2, we can start by considering the prime numbers 2 and 3. The difference between these two prime numbers is indeed 2.
Therefore, a possible pair of prime numbers where the difference is 2 is (2, 3).
