comment How to calculate the probability density function for joint distribution?
One way to see this is through characteristic functions. There is a theorem which says that $X =_d Y$ iff $X$ and $Y$ has the same characteristic function. So if you write down the characteristic function of the sum of two independent normal random variable, you will see it is indeed a char. function of a normal distribution.
