It seems a bit artificial to me! But there are many
possibilities for related sequences that are not in the OEIS.
Let sp(n) = Sum of primes <=n
What about sp(n)*pi(n) ? Sum_{d|n} sp(d) ? BINOMIAL or
BINOMIALI (= inverse binomial) transforms of sp(n) ? etc
(see the "transforms" file)
incidentally sp(n) is A034387, pi(n) is A000720
Best regards
Neil
