Tables of i and n for each prime p, and all 1<n<p, all naturals, such
that i is minimal and i.p+/-n are simultaniously prime.
e.g. p=13, n=12 has i=143, as 1847 and 1871 (1859+/-12) are both
A little challenge...
Find the i values such that i.p+/-n are _consecutive_ primes.
No particular reason, just a whim, and as the number or results
increases quadratically in the value of the prime chosen, I'm most
interested in the n=p-1 results, as they require the largest
composite run, and are thus heuristically hardest.
