COMMENTS

Except for 3 no other prime has a digit sum which is a multiple of 3. Hence the possible digit sums are 2,3,4,5,7,8,10,11,13,14,16,..., etc. Conjecture: For every possible digit sum there exists a prime.
For n > 2, this is (conjecturally) the smallest prime with digit sum A001651(n).  Lekraj Beedassy, Mar 04 2009
