Prepare pasta according to package directions; add green beans to pot 3 minutes before pasta will be ready.
Bring a large pot of salted water to a boil over high heat. Add shrimp and return to a boil. Boil for 1 minute and then drain.
Combine shrimp, tomatoes and corn in a medium saucepan. Add olive oil and season with salt and pepper. Bring mixture to a simmer over medium heat. Cover, remove from heat and set aside until pasta and beans are done.
Set aside 1 cup pasta cooking water and then drain pasta and beans. Toss pasta and beans with shrimp mixture; if pasta looks dry, add reserved water in 1/4-cup increments until desired consistency is reached. Season with salt and pepper.
