numrical integration in six dimension

Hi,
I want to perform following numerical integration in 6 dimension.
I = 0.5*(x1^2+x2^2+x3^2)-40000/(x4^2+x5^2+x6^2)^1.5

I want to integrate I w.r.t. x1, x2, x3, x4, x5, x6, each from -inf to inf.
It should be noted that the integrand is converging. So, a finite integral should be obtained. One way to do integration is to integrate out x1,x2,x3 first, using triplequad. And then integrate the rest. But one can see that 0.5*(x1^2+x2^2+x3^2) is diverging even though I as a whole is converging. So, is there any way to perform this integration.
Thanks.
