# Dealing with primes

Let $$P$$, $$Q$$ and $$R$$ be primes with $$Q$$ not equal to $$R$$ such that $$(4 +PQ)$$ and $$(4 +PR)$$ are perfect squares. If there is(are) $$n$$ possible pair(s) of solutions then there are $$n$$ possible sum(s) of the pairwise primes. Find $$n+$$ the possible $$n$$ sum(s) of pairwise primes $$P$$, $$Q$$ and $$R$$. Consider $$(P, Q,R)$$ and $$(P, R, Q)$$ as one pair.
