That time you got a negative number in the list", there should be at least another negative number there-- 2,4,2,4,2... differences would be 2,-2,2,-2,...

(Heck, DARPA will even give you a grant to look into the RH if you think you have an interesting handle on it; it's on their list of 23 big problems, too.)

Hard to prove, but <i>who cares?</i> I usually have a great deal of interest in mathematical curiosities. This one... nah. There are far more complicated problems in the mainstream of mathematics that will probably be resolved sooner, not just because they are related to previously solved problems, but also because they matter more.
