Does Zhang's result have any useful implications for previous polymath project, "Deterministic way to find primes"?

comment Sequences of Coefficients in $a p^i + b q^j = 1$
For every (i,j) pair there a lot of pairs (a,b) satisfacting this equation, so are there any other restrictions? Also, how explicit formula for them should be? Is something like $a_{ii}=p^{-i}\mod q^i$ acceptable?
