Bieber's New Numbers

Our January 31 issue features singing sensation Justin Bieber on the cover and a puzzle to figure out how many users follow his comments on Twitter. Now he has even more than we wrote that puzzle! This morning, the number was 2x4 + 5x4 + 386,028 with x = 31. How many followers does Justin have now? If you've already done the cover puzzle, compare your new answer to the answer on the cover!

Justin Bieber had 6,850,675 followers last Monday. (Today, he has 6,946,850.)
