%N Numbers n such that the sum of first n prime powers (A025475) is divisible by n.
%C a(17) > 146306913. There are 146306913 prime powers <= 2^63. - _Donovan Johnson_, May 16 2013
%e The sum of first 9 prime powers is 1 + 4 + 8 + 9 + 16 + 25 + 27 + 32 + 49 = 171. Because 171 is divisible by 9, the latter is in the sequence.
