We obtain asymptotic formulas for the number of odd integers up to x that can be written as a product pq, with p, q both primes, satisfy Sg(p)≡Sg(q)≡amodb(b⩾2,a∈Z)\documentclass[12pt]{minimal}\usepackage{amsmath}\usepackage{wasysym}\usepackage{amsfonts}\usepackage{amssymb}\usepackage{amsbsy}\usepackage{mathrsfs}\usepackage{upgreek}\setlength{\oddsidemargin}{-69pt}\begin{document}$$S_g(p) \equiv S_g(q) \equiv a ~\mathrm{mod}\,~ b\ (b \geqslant 2, a \in {\mathbb {Z}})$$\end{document}. So, we observe a large bias amongst such integers.
