Does it have to work for 15-digit AMEX payment card numbers too?

Recommend avoiding storing credit number, or store them as the masked value.

I wrote a function that you can use to make this job: you can pass to this function any number, the function calculates the modulo 10000 class of the number (i.e. the rest of the division by 10000) in other words the last four digits of your number. Then the function concatenates XXXX-XXXX-XXXX- and zeros as needed.
