How many even numbers greater than 40000 that can be formed from the following digits 1,0,2,4,6,7,8

Answer 1

4, 6,7, 8 in the ten thousands
0,1,2,4,6,7,8 can be used in the thousands
hundreds and tens could use any of the digits

ones would have to be 0,2,4,6,8

if we can repeat the digits then
4 times 7 times 7 times 7 times 5

The only problem is that we don't want to have 40000 snd this could happen with the above. Can you think about what you would have to do to eliminate that possibility?
