Final answer:
The sum of any two prime numbers except 2 is always an even number.
Step-by-step explanation:
The sum of any two prime numbers except the number 2 is always an even number (C). This is because all prime numbers greater than 2 are odd, and the sum of an odd number and an odd number is always even. For example, the sum of the prime numbers 3 and 5 is 8, which is an even number.
