Subject: divisors of an integer
     
Carl Pomerance has pointed out that there is a paper of Erdos,
Elem. Math. 28 (1973), 83-86, which deals with this question.
In particular, Erdos shows that the density of even integers
that are equal to the sum of aliquot divisors of some integer
is stricly less than 1/2.
