What year did Goofy come to Disney?

Goofy's first appearance was in the 1932 short film "Mickey's Revue," but his name was originally "Dippy Dawg." He didn't become "Goofy" until 1933 in the short film "The Whoopee Party."

So, depending on how you define his "arrival," the answer is either 1932 or 1933.
