I thought it was the white that has the sulphur. A quick Google seems to confirm that, but more to the point I find the white has a hint of it in its flavour.
According to this page [1] 'Each egg yolk contains 0.016 milligram of sulfur, and the white contains 0.195 milligram, according to B. Srilakshmi, author of "Food Science." '
If I googled "egg white sulfur" you would have a point about confirmation bias. But I just googled "egg sulfur" and clicked on the top few results, all of which either pointed to the white or didn't mention either way.

A quick google will equally confirm whichever answer you are trying to confirm. Some sites say it's the yolk. Others say it's the white.
Opposite example:
List of Foods That Contain Sulfur
Eggs. The yolk portion of an egg is high in sulfur.

I have yet to find anything reliable, like a .gov site, addressing the question.
Sulfur issues run in my family. I have to limit my consumption of sulfur.
It's the yolk that's an issue for me, not the white, fwiw.
