Attempting to understand this sequence better I have just posted a (hopefully) complete list of composites derived from Fibonacci numbers with prime indices, up to index 997:


There appear to be an Eulerian number < http://oeis.org/A000295 > of solutions in each case. Antti's composites will of course be the sorted collection of all these solutions to infinity. My question is still how one might know that smallish solutions (say, up to a given size) will not come from unsolved, future Fibonaccis.
