Comment(by kevin.stueve):

 Take note of Remark 4 in Introduction to twin primes and Brun’s constant
 computation, by Pascal Sebah and Xavier Gourdon at
 numbers.computation.free.fr/Constants/constants.html (July 30, 2002)

 "Remark 4 The function Li2 (n) occuring in (1) may be related to the
 logarithmic integral Li(n) by the trivial relation

                       Li2(n) = Li(n) +   2 / log(2) - n / log(n)."
