def is_prime(n):
    if n < 2:
        return False
    if n == 2:
        return True
    if n %2 == 0:
        return False


    i = 3
    while i*i <= n:
        if n%i == 0:
            return False
        i += 2
    return True


def reverse_num(n):
    s = str(n)
    s = s[::-1]
    return int(s)


def main():
    line = input()
    L = eval(line)
    res = []
    for n in L:
        if is_prime(reverse_num(n)):
            res.append(n)


    if res:
        print('List of prime numbers:', res)
    else:
        print('No prime number')



if __name__ == '__main__':
    main()
