%N Values of m where A020482(m) != A060308(m-1).
%C Usually the greatest p with p,q both prime, p+q = 2m, is equal to the largest prime <= 2m-2, but not always. These are the exceptions.
%C Almost all natural numbers are in the sequence so the above comment is misleading in general, and only fitting for small numbers. - _Jens Kruse Andersen_, Jul 13 2014
