Yes, I do that all the time. For example: http://svn.clifford.at/handicraft/2017/smtcode/smtcode.smt2 … solves http://svn.clifford.at/handicraft/2017/smtcode/smtcode.jpg … And of course also harder puzzles like this one: https://twitter.com/oe1cxw/status/954697912528855040 … But I'm still waiting for a solver that can solve this out of the box:pic.twitter.com/mkMrmwlXl7
Yes, there are specialized elliptic curve solvers of course. But nothing generic that just looks at that (i.e. an equivalent set of formal constraints) and knows what to do with it.
Ohhh yes, that problem is a doozy. Good answer on Quora about it; the answer is like dozens of digits long if memory serves. I'd thought about trying that problem and seeing if z3 chokes on it, but seems like you already did :P.

Re trying that problem: No, I did not try it. I just know that this is not the kind of stuff that SMT solvers are good at. However, I just wrote a short smt2 file in case you want to play with it: http://svn.clifford.at/handicraft/2018/ecsmt/ecsmt.smt2 …
But z3 even has a hard time with it when you assert concrete values for two of the three variables. And yices doesn't even support a logic that would allow this kind of arithmetic afaict. But you can use this to check the solution I gave above by asserting the solution.
Ahh right. I was gonna do something a little less restrictive like: (assert (> A 4373612677928697257861252602371390152816537558161613618621437993378423467772030)) etc Can't make the solver's job too easy, right?
