About the sum of the reciprocals of the twin primes

The sum of the reciprocals of the primes verifying $p_{n+1}=p_{n}+2$ (pairs of primes which differ by $2$) converges to a finite value
$$B_2=sum_{n} frac1{p_{n}}+frac1{p_{n}+2}>0$$
In other words, the sum either has finitely many terms or has infinitely many terms but is convergent. In 2004 Thomas Nicely gave $$B_2=1.9021605825820±000000001620$$ based on all twin primes less than $5×10^{15}$.
My question is: How one can prove rigorously that $B_2<2$. The estimation of Nicely is not a mathematical proof.

Effective version of Brun's theorem are bounds on $sum_{n > x} frac{1_{p_n+2 in P}}{p_n}$
