Well 2 is the outlier because it’s the only even prime. It might not be “special” but it is unique out of all of the prime numbers.
“even” just means divisible by two. So it’s not unique at all. Two is the only prime that’s even divisible by two and three is the only prime that’s divisible by three. You just think two is a special prime because there is a word for “divisible by two” but the prime two isn’t any more special or unique in any meaningful way than any other prime.
It’s unique because all the others are odd numbers. This is crazy that you’re trying to argue this.
Of couse all the others are odd because otherwise they wouldn’t be prime. All primes after three are also not divisible by three… “magic”. The only difference is that there are is no word like “even” or “odd” for “divisible by three” or “not divisible by three”.
