There aren't any. 2 is the only even prime number, so no other even numbers can be prime. There can be no even numbers between 30 and 50 that are prime.

All prime numbers are not odd numbers. 2 is an even prime number, and it is the only even prime number because all other even numbers have 2 as one of their factors.

2 is the only even prime number, because all other even numbers can be divided as 2.

There are infinitely many prime numbers. There is only one even prime number, which is 2, because all other even numbers are divisible by 2 and thus are not prime. So, there are infinitely many odd prime numbers and only one even prime number.

Yes it can. 2 is an even number and it is prime.

There is a simple counterexample: the number 1:1 is an odd numberthe first prime is 2 (not 1, see below) which is bigger than 1 so 1 cannot possibly be the sum of two primes.There are plenty of other counterexamples:The sum of two odd numbers is even;All prime numbers except 2 are odd;When adding two prime numbers together, to get an odd result one of them must be even, namely 2;So any odd number that is 2 more than a composite number will not be expressible as the sum of two primes. examples: 11, 17, 23, 27, 29, 35, 37, ...Another counterexample is the number 3:3 is an odd number3 can only be made by 2 + 11 is not a prime (see below)A prime number is a number that has exactly 2 distinct (different) factors.The number 1 has only 1 distinct factor (the number 1) and so is not a prime number; the first prime number is 2.
