So if you add two odd numbers, you have a bunch of pairs and the two lonely units make a final pair, and the sum of two odd numbers is even.
Why is 2 a prime number?
The number 2 is prime. But if a number is divisible only by itself and by 1, then it is prime. So, because all the other even numbers are divisible by themselves, by 1, and by 2, they are all composite (just as all the positive multiples of 3, except 3, itself, are composite).

Are all multiples of 2 even?
When we multiply 2 by another number, the product is called a multiple of 2. For example, 2 × 0 = 0, 2 × 1 = 2, 2 × 2 = 4, 2 × 3 = 6, 2 × 4 = 8, etc. Thus, every multiple of 2 is called an even number or the number which has 2 as one of its factors is known as an even number.

Is the GCF of 2 even numbers always even?
It is true that the GCF of any two even numbers is always even. GCF refers to the greatest common factor that two or more numbers have, and obviously it is going to be an even number. Take 18, 30, and 42 as your example – their GCF will be 6, which is an even number, as are those three numbers.
Is 22 an even number or odd number?
