%N A036382 Odd split numbers: have a nontrivial factorization n=ab, LCM[ a,b ]=1,
so that g(a)+g(b)<=g(n), where g(x) is binary order of x.
%C A036382 All even numbers are split numbers, except that prime powers - here powers
of 2 - are by definition excluded.
%e A036382 s=39 is a split number since s=39=3*13, LCM[ 3,13 ]=1 and g(3)+g(13)=2+4=g(39).
