Even Prime
The unique even prime number 2. All other primes are odd primes. Humorously, that means 2 is the "oddest" prime of all.
The sequence 2, 4, 6, 10, 14, 22, 26, 34, 38, ... (OEIS A001747) consisting of the number 2 together with the primes multiplied by 2 is sometimes also called the even primes, since these are the even numbers 
that are divisible by just 1, 2, 
, and 
.
