Windows 8 build 8437 is a pre-RTM build of Windows 8. Some screenshots were found of this build on Chinese websites BetaWorld and Coolapk. It is only known to exist in the ARM architecture and was supposedly uploaded to the Chinese website BetaWorld on 30 September 2019, but at the moment this cannot be confirmed or refuted as it is not publicly available.
