How many even numbers greater than 5,000 can be formed using the digit 1,2,4,5,6 if no digit is used more than once?
---------
All 5 digit numbers are > 5000.
---> 5*4*3*2*1 = 120 numbers.
---------
No 3 digit #'s are > 5000.
-------
The 1st digit of 4 digit numbers must be 5 or 6.
--> 2*4*3*2*1 = 48 numbers.
120 + 48 = 168
