Question

Is the sum of two prime numbers is always even?

Answer 1

Define prime numbers :

A number that can be divided exactly only by itself and $1$, is known as prime number. Every prime number is an odd number except $2$.

We know that adding two odd numbers always results in an even number, whereas the addition of an odd number with $2$ will always result in an odd number.

Hence, we can conclude that the sum of two prime numbers except $2$, are always even.
