Is the uptime really technically true? Sure, the Voyager has been operating for 40+ years, but all embedded systems must have watchdog timers. And given how hostile the space environment is, I'll be surprised if the main system hasn't been reset by a watchdog timer for a couple of times to recover from fault conditions, thus the actual uptime must be much less than that.
