Using https://e2b.dev/docs, complete the following task:

Using E2B, build me a script that runs a multi-step computation inside a E2B sandbox:
        
1. Use the E2B Python SDK to create/connect to a sandbox
2. Inside the sandbox, execute the following pipeline:
   a. Install the `sympy` package using pip
   b. Run a Python script that:
      - Computes the 10th Fibonacci number iteratively
      - Uses sympy to check if that number is prime
      - Prints the result as JSON: {"fibonacci_10": <number>, "is_prime": <boolean>}
3. Capture the sandbox execution output and print it to stdout

All computation must run inside the E2B sandbox, not in your local Python process. Do not use subprocess — use the E2B SDK's execution primitives.
