There is no such number. I went through and tried all of the possible numbers, none of them work.

Here is a short way to do so: If the digits are within 4 of each other, then the number's reversal will be too close. However, if they are 6 or above away from each other, the number's reversal will be too far away. So the digits must be 5 apart. Since the first digit must be larger, the possibilities are 50,61,72,83, and 94. None of these match the last requirement, so there is no such number.
