LV 426 Warning Beacon & The Engineers In Prometheus

I've been reading and enjoying the conversation here for a couple of months now, and I'd like to broach a subject that has been on my mind recently.
Based on what I've read here, it seems that LV426 and LV223 are relatively close to each other (in cosmic terms). If the Juggernaut ship in Alien is much older than the one in "Prometheus", why has remained undisturbed up to the point that the crew of the Nostromo stumbles across it?
"Prometheus" makes a point of explaining that a crew of Engineers were alive on LV423 and planning a visit to Earth around 2,000 years ago, supposedly much later than when the ship on LV426 crashed. The LV426 ship had an distress beacon which awoke the crew of the Nostromo from hyper-sleep. Does it not make sense that the beacon would also have been discovered by the ill-fated crew of Engineers in "Prometheus", and that they would have taken the time to investigate the fate of their fallen brother? If not, the beacon would indeed have to be a warning for other Engineers to avoid the crash site and the Xenomorph eggs.
If the Engineers are using the Xenomorphs as a weapon to annihilate entire planets, why not stop by LV426 to pick up the lot of them? The warning beacon would seem to indicate that the Engineers deem the Xenomorphs far too dangerous to deal with one-on-one, and they would rather let the cargo hold full of eggs gather dust for tens of thousands of years than to risk further contact.
I have seen some people here on the board and on several blogs asserting that the Xenomorph in the Alien quadriology is an earlier, less evolved version of the creature, and the the Engineers of "Prometheus" are working to create something further evolved. Perhaps the abandoned egg cargo on LV426 may help to support this theory?
Cheers!
