CI: MacPython failing TestPandasContainer.test_to_json_large_numbers
- [x] closes #35147
- [x] passes `black pandas`
- [x] passes `git diff upstream/master -u -- "*.py" | flake8 --diff`

I am OK with this I think we can add these tests in when we actually make changes to the readers. @jreback ? can you make this a separate test and just xfail them? Hello @arw2019! Thanks for updating this PR. We checked the lines you've touched for [PEP 8](https://www.python.org/dev/peps/pep-0008) issues, and found:



There are currently no PEP 8 issues detected in this Pull Request. Cheers! :beers: 

##### Comment last updated at 2020-07-15 01:42:21 UTC Pushed a commit xfailing the test for 32-bit. Opened https://github.com/pandas-dev/pandas/issues/35279 to track it. My commit broke the other case. Will get it fixed up here soon. OK, just skipping that test on 32-bit systems, under the assumption that it's supposed to return an int64 dtype when `sys.maxsize - 1` fits in an int64. Leaving updating the test to https://github.com/pandas-dev/pandas/issues/35279. Merging to get CI passing at MacPython. Thanks @arw2019.
