Simple Maths Riddle 5

Here's a special one for you!




I am prime, I am composite



Sum my digits and half; I'll be perfect!



Don't multiply them, I won't yield a thing



But don't worry, it's only the beginning!




What am I?

          $2019$




          I am prime, I am composite




          Prime as in beginning and composite as $2019 = 3cdot673$




          Sum my digits and half; I'll be perfect!




          $2 + 0 + 1 + 9 = 12$, then $12/2 = 6$




          Don't multiply them, I won't yield a thing

          I'm thinking it might be




          39


          (3+9)/2=6, a perfect number as its factors sum to the number itself: 1+2+3=6


          3 is prime and 9 is composite


          Multiplying them won't yield just a thing, it yields 3*9=27 things


          I am a bit hung up on this but perhaps 39 is the beginning of a sequence where these rules hold true (i.e., it's the smallest number produced by these rules). Or perhaps it's the first two of this series: 3^1, 3^2, 3^3, ...

          Partial:



          Are you




          1?




          I am prime, I am composite




          Some say 1 is prime, some say it is composite




          Sum my digits and half; I'll be perfect!




          ? Perfect number?




          Don't multiply them, I won't yield a thing




          any n*1 yield n




          But don't worry, it's only the beginning!
