ignore this question all gone Solving Stokes Equations using 3D Fourier transforms

sorryHow do you calculate the inverse Fourier transform of $r_i$ ignore this question$\frac{k_ik_j}{k^4}$. I know it has to be a matrix of the form $=δ_{ij}A(r)+r_ir_jB(r)$, but how do you calculate the functions A(r) and B(r)?

I am trying to use Fourier transforms to find the Oseen tensor (a solution to Stokes equations).
