Conjecture: for every m greater than a(n), there are more than n primes between m and m+sqrt(m); true if a(n) less than 1000000.

EXAMPLE
a(3)=2558 because there are three primes between 2558 and int(2558+sqrt 2558)= 2608 and for every larger number there are more than 3 primes in the respective interval.
