Number theory problem

I was wondering if anyone could give me some help with this problem. I have to
prove that all but finitely many positive even integers can be expressed as one
of the following:

x= -(p+q+r) (mod pqr) where p,q,r pairwise relatively prime and 2|pqr

OR

x= pqr-(p+q+r) (mod 2pqr) where p,q,r pairwise rel. prime and all odd.


Thank you. (BTW, this is not possible with a finite number of primes, for
example, cannot get -8 (mod p1p2p3...pn)).
