Thanks for the answer.  I should have phrased my question more
carefully. I was already aware of the comment by Robert Wilson, I was
asking for references for that comment, i.e. where is it proven that
the first differences of a_n are always 2 or 3.  Since then, I found the 
following, that contains a proof apparently by Tomas Schonbek:

Thanks for the pointer.  This question turns out to be complicated
enough to be assigned for a mini-project.  In that case I will make 
sure to have the students properly cite the OEIS.

Actually, I am using the OIES for an (unrelated) paper I am writing and
I will make sure to cite the relevant sequences.

Best,
