Palindromic primes in base 16

Trivial modification of Palindromic primes task.

say "{+$_} matching numbers:\n{.batch(10)».fmt('%3X').join: "\n"}"
    given (^500).grep: { .is-prime and .base(16) eq .base(16).flip };

Output:

13 matching numbers:
  2   3   5   7   B   D  11 101 151 161
191 1B1 1C1
