The first rule for Schengen visa is your main stay, which usually is the longer one, but can also be the one with the more important meetings.
So, even with the days as you mention, it may be that the stay in the Netherlands is way more important to you and that you are right in applying at the Dutch embassy.
Please, do remember that you will leave and re-enter the Schengen zone and as such need a multiple entry visa.
The only way around that would be not returning to Hungary, if that is possible.
