Best ResponseYou've already chosen the best response.1Here is a sequence for up to 100th prime of (p,q) {{5, 3}, {7, 5}, {13, 11}, {19, 17}, {31, 29}, {43, 41}, {61, 59}, {73, 71}, {103, 101}, {109, 107}, {139, 137}, {151, 149}, {181, 179}, {193, 191}, {199, 197}, {229, 227}, {241, 239}, {271, 269}, {283, 281}, {313, 311}, {349, 347}, {421, 419}, {433, 431}, {463, 461}, {523, 521}}

Best ResponseYou've already chosen the best response.0\[pq + p + q + 2 = p^2\]\[q=\frac{p^2p2}{p+1}=\frac{p^2+p2p2}{p+1}=p2\]

Best ResponseYou've already chosen the best response.1\[pq+p+q+2=p^2\]\[p(q+1)+q+2=p^2\]\[(p+1)(q+1)+1=(p+1)(p1)+1\]\[q+2=p\]\(p\) and \(q\) are twin primes... But it's an open conjecture on whether there are an infinite number of twin primes... http://mathworld.wolfram.com/TwinPrimeConjecture.html
