What 5 digit number am I thinking of. It has 2 prime digits. Digit 3 is the highest number. Digit 2 is lowest. Digit 5 is between digit 2 and digit 1 and is half of digit 4. There are no duplicates. Digit 1 is 1 smaller than digit 3. Digit 1 is higher than the sum of digits 4 and 5. Don't forget that 1 isn't prime.
