Can you find an even number greater tha 4 which cannot be expressed as a sum of two odd numbers ?

Explanation

The number can use digits 0,1,2,5,6,8 and 9 because they can be recognised as digits whey they are see inverted.
A number can't beginn with, therefore all numbers having at unit's digit should no be counted. (when those numbers will be read inverted they will begin with).
