%N Numbers that are the sum of distinct primes with prime subscripts.

%C Dressler and Parker proved that every integer > 96 is a sum of distinct terms of A006450 (primes with prime subscripts).

%C The complement is A213356.

%D R. E. Dressler and S. T. Parker, Primes with a prime subscript, J. ACM, 22 (1975), 380-381.

%e Prime(Prime(1)) + Prime(Prime(2)) + Prime(Prime(3)) = Prime(2) + Prime(3) + Prime(5) = 3 + 5 + 11 = 19 is a member.

%Y Cf. A006450, A185724, A213356, A214296.
