In a new walking challenge, I decide to make a move for each integer from 1 to 30. On the first move, I stand still. For subsequent moves $n$ (2 ≤ $n$ ≤ 30), I will take two steps forward if $n$ is prime and three steps backward if $n$ is composite. After completing all 30 moves, I walk straight back to my starting point. How many steps is my return journey?
