Splitting work to pass through the integer overflow error

[Yixraie]

Yes I know it would be very long to crack. But I'm pretty sure there are a lot of malicious hackers in the world who brute force longer passwords than that. I think they have access to a lot of computers at a time, and make them work together by dividing the work. But here it seems impossible to divide it.
What's the explanation technically? Why hashcat block because of the mask, whereas I don't want it to test every combinations but just a reasonable part?
