如何在 Bigquery 中将字符串拆分为带空格分隔符的行？

Question

I'm having a hard time understanding regular expression.

I have a table mydataset.city

id | city
---+----------------------------------------------    
1  | LOS ANGELES     NEW YORK     INDIANAPOLIS

Between each cities contain 5 spaces as delimiter.

id | city
---+------------

1  | NEW YORK
1  | INDIANAPOLIS

How can I write this in bigquery?
