    Yes, you can specify the minimum length:

    /(\d{4,})/

    The brace syntax accepts a single number (as you used) indicating the exact number of repetitions to match, but it also allows specifying the minimum and maximum number of repetitions to match, separated by a comma. If the maximum is omitted (but the comma isn’t), as in this answer, then the maximum is unbounded. The minimum can also be omitted, which is the same as explicitly specifying a minimum of 0.
