False.
Even numbers are integers that are divisible by 2. Composite numbers are integers greater than 1 that have more than two factors (1, the number itself, and at least one other factor).
While most even numbers are composite, the number 2 is a prime number, not a composite number. A prime number has only two factors: 1 and itself. Since 2 is only divisible by 1 and 2, it fits the definition of a prime number. Therefore, not all even numbers are composite. All other even numbers greater than 2 are divisible by 1, 2, and themselves, thus making them composite.
