"I've created from 1098 candidate p < 10000 a list of composite divisors. Only 260 of these Fib(p) are fully factored..."

Correction: There are in fact 1203 candidate p < 10000. I missed 105 composite Fib(p) where not a single factor is known. Also 263 are now fully factored. I found 3 recent factorizations in factordb.com. I've created this table: http://chesswanks.com/num/CompositePrimeIndexFibonaccis.txt
