%N A062339 Primes whose sum of digits is 4.
%C A062339 This is a subsequence of A062338. Is this sequence (and its brothers 
               A062337, A062341 and A062343) infinite?
%C A062339 10^A049054(m)+3 and 3*10^A056807(m)+1 are subsequences. A107715 (primes 
               containing only digits from set {0,1,2,3}) is a supersequence. Terms 
               not containing the digit 3 are either terms of A020449 (primes that 
               contain digits 0 and 1 only) or of A106100 (primes with maximal digit 
               2) - and thus terms of these sequences' union A036953 (primes containing 
               only digits from set {0,1,2}). - Rick L. Shepherd (rshepherd2(AT)hotmail.com),
