In this paper, we consider D = Z[θ], whereis a squarefree integer, and we proved that the number R(y) of representations of a monic polynomial f (x) ∈ Z[θ][x], of degree d ≥ 1, as a sum of two monic irreducible polynomials g(x) and h(x) in Z[θ][x], with the coefficients of g(x) and h(x) bounded in complex modulus by y, is asymptotic to (4y) 2d−2 .
