Unfortunately, my machine doesn't have enough memory to look for the earliest difference > 1 billion.
This takes 23 seconds to run on my machine (core i7, 32GB RAM, Ubuntu 20.04) which is what I'd expect as Wren is typically 4 or 5 times slower than Phix.
If anyone's wondering why I can't sieve 5 billion numbers with this much RAM, the reason is that bools require 8 bytes of storage in Wren (all value types do) compared to only 1 byte in most statically typed languages (or even 1 bit if they support bitarrays).
