no because 31 is not an even number. Therefore an even number can not be a factor of it. 31 is a prime number so the only factors it has are 1 and 31

No, as all prime numbers are odd, excluding 2, and when you add two odd numbers you get an even number. This even number can't be a prime number as it will be divisible by 2. 101 and 31 are both prime, but 101+31 is 132.
