Answer:
2 and 3.
Explanation:
To get a product of an even number, you have to either multiply two even numbers together or multiply an even number and an odd number together.
There is only one even prime number- 2.
Therefore, you can have any pair of prime numbers that, when multiplied together, get an even number as long as one of those numbers is 2.
2 and 3 work, as well as 2 and 5. The list goes on and on. Just choose a random prime number (that's not 2) and pair it with 2. It is guaranteed that when you multiply those two numbers together, you will get an even number.
