%N A000001 Even numbers n such that (n+2)|(n+2^n).
%C A000001 Most numbers n such that (n+2)|(n+2^n) are
odd. The sequence gives  five known (at present, to
me) even such numbers. The fifth term is due to Max
Alekseyev (maxal(AT)cs.ucsd.edu), Sep 20 2006. There
are probably many other terms between 4th and 5th
terms.
