It will be seen that this is converging to the correct answer though we'd need to add a lot more primes to obtain a valid 11th digit.

This agrees with the Phix entry that the 1,000th digit after the decimal point is '8' after rounding (according to OEIS it's actually '7' but the next one is '7' also).
