I believe that is correct. In addition I think that G must have a
subgroup for every prime power which still divides the order of G.
Weather or not the composite factors have associated subgroups will
indeed depend on the particular group G represents.
As an example consider the group of rotations of a tetrahedron. It has
12 elements but no subgroup of order 6.
