if you mean what three prime numbers add up to a prime number then the answer is : 5 + 7 + 11 = 23
The smallest prime number, of course, is 2. The smallest prime number whose digits add up to 2 is, of course, 2. The next-smallest is 11. It is left as an exercise for the reader to determine whether the other numbers whose digits add up to 2 (e.g. 101, 1001, 10001) are prime.
no 11 is not a perfect number because when u add the factors the don't add up to 11
23+11+61=95 :)
