The primeodds have just been raised! (Actually the odds remain the same, it is my estimate thereof which has increased.)

That statement neglects that by construction, the remaining terms are not divisible by 3 or 5, i.e. if the factorization is indeed random (or at least random as far as aggregate odds are concerned), it is so w.r.to primes > 5. Thus my Pariloop estimates all need to multiplied by (3/2)*(5/4) = 15/8, i.e. are nearly doubled.
Of course those are the naive odds  the conditional odds given
no primes found below 10^5 are still quite low for the 10^5  10^6 range, around 10%.
