Number of positive integers $ (m, n) $

Find the number of positive integers $ (m, n) $ For who $ m choose n $$ = 1984. $

1984 $ = 2 ^ 6 times31 $

I wrote the binomial coefficient expression, but I could not deduce anything from the equation. I've also tried to write 1984 $ as $ 32 times 31 times $ 2 but not use. Please help.
