10^13000+10029 is a probable prime.

This number is right where it should be to be prime.

Actually, these numbers are not that difficult to
find:

Set up two searches (1) an up-run and (2) a down-run
both from
10^x + x + adj(if dessired)

this corresponds to the fact that the average distance between
primes is ln(y) and ln(10^x)/2 = x * ln 10 / 2 approx. = x
the division by 2 corresponds to the fact that on the average 10^x
will be half way between the two primes. The adj. term can be
added to take account of the fact that the distribution of primes
is highly right-skewed.
