In the US, most banks will happily allow you to withdraw money in any currently circulating form. That amounts to bills in denominations of 1, 2, 5, 10, 20, 50, or 100 dollars, or coins in denominations of 1, 5, 10, 25, 50, or 100 cents.
There are some problems here. You need to specify 8 million what. Another problem is that there really are no dollar bills at all in 8 million anything, even 8 million dollars, unless you have accumulated that much cash in one dollar bills. No one in his right mind would accumulate that much money in one dollar bills unless it is for some kind of publicity stunt or Guiness record.
