For what it's worth, the primes program is an old V7 warhorse that hasn't
been touched in years (since 1983 at least). It gives the same even numbers on
our Unix machines around here as it does on our Plan 9 systems. Since the
program is old and venerable, like its author, and since the primes you're
asking for are close to the documented limit of its capabilities, I have only
one suggest: look for smaller primes.
