In[8]:= 
expr=(a==1001&&b==1001000)||(a==1002&&b==501000)||(a==1004&&b==251000);
{a,b}/.{ToRules[expr]}

Out[9]= {{1001,1001000},{1002,501000},{1004,251000}}

If expr is indeed the result of a Reduce command, I think it is very 
likely that instead of Reduce you could have used Solve (it has quite a 
lot of new features) in order to obtain the rules immediately.

Kind regards,
