In this case, if you really want to be able to edit the constituents, you could represent your number by a more complex object which allows you to access its 4 constituent parts through an indexer. That way it's just a simple binding and the object that keeps the 4 parts is accessed and can piece together the whole number:

public class MyNumber {
  public int this[int index] {
    get { /**/ } set { /**/ }
  }
  public string FullNumber { get { /**/ } }
}
