The Bears began their season at Lambeau Field for a Sunday night battle with their hated rival, the Green Bay Packers.  After a scoreless first quarter, Chicago trailed early as Packers kicker Mason Crosby got a 52-yard field goal.  The Bears would respond with safety Danieal Manning sacking quarterback Aaron Rodgers in his own endzone for a safety, but Green Bay would respond as running back Ryan Grant got a 1-yard touchdown run. Chicago would take the lead in the third quarter as quarterback Jay Cutler completed a 36-yard pass to wide receiver Devin Hester, along with kicker Robbie Gould making a 47-yard field goal.  Afterwards, the lead went back and forth in the fourth quarter.  Crosby would kick a 39-yard field goal, while Gould nailed a 21-yard field goal.  Afterwards, the Packers took the lead again as Rodgers completed a 50-yard touchdown pass and the following two-point conversion to wide receiver Greg Jennings.  The Bears tried to rally, but an interception ended any hope of a comeback. Cutler's 4 interceptions were the most he had thrown in one game of his career, until week 10 against the 49ers.
Question: How many yards longer was Crosby's longest field goal over Gould's longest one?
