Answer for March 28.......sorry for the delay

Largest - 35772
Smallest - 32257

Prime digits are 2, 3, 5 and 7. Taken as pairs, the only combinations that fit criterion 2 are:
22, 25, 27, 32, 33, 35, 52, 55, 57, 72, 75 and 77.
Of that list, 33 is the only number that contains a 3 as the second digit and so for criterion 3 to be satisfied, 3 can only appear at the start of the 5-digit numbers. From there it is simply a matter of choosing the next digits using the list above so that criterion 2 is satisfied, making sure that criterion 3 is also satisfied.
