Here is the Gould 1981 version:

You will find that, the better your hi-fi, the more obtrusive Gould's moaning along becomes (one producer threatened to gag him). Nevertheless, as John says, this is a superlative performance, and this video allows you to see what a wonderful technician Gould was - given the famously low height of his piano chair, you sometimes think that he's going to play a third line with his nose. The contrapuntal lines are played with a wonderful clarity and crispness. The Goldbergs were written for harpsichord with double manuals, so hand crossing is no problem. On a single manual piano it is a problem, so it's fascinating to see how it's done - watch the fun from 7:14 onwards.
I agree that Angela Hewitt's is top-class, as is Murray Perahia's. For the original harpsichord version, Trevor Pinnock's version is excellent.
