Split If not certain word and not first 4 characters

Question

I have a column using the following structure:

YYYY Month Corporate Word1 Word2
YYYY Month Corporate Word1 Word2 Word3
YYYY Month Word1 Word2
YYYY Month Word1 Word2 Word3

I currently have a formula that splits each of the words in that string into separate cells.

=IFERROR(SPLIT(A2," "),"")

This is what I get now:

String	Split Formula	Split Result2	Split Result3	Split Result4	Split Result5	Split Result6
YYYY Month Corporate Word1 Word2	YYYY	Month	Corporate	Word1	Word2
YYYY Month Corporate Word1 Word2 Word3	YYYY	Month	Corporate	Word1	Word2	Word3
YYYY Month Word1 Word2	YYYY	Month	Word1	Word2
YYYY Month Word1 Word2 Word3	YYYY	Month	Word1	Word2	Word3

I would like to ignore the year and any mention of "Corporate". Would also appreciate a formula that populates for the whole column instead of having to copy down the same formula. When I try the following:

=ARRAY_CONSTRAIN(MAP(A2:A,LAMBDA(x,IFERROR(SPLIT(x," "),""))),COUNTA(A2:A),1)

It only returns the year. No other word is extracted.

This is what I would like the end result to be:

String	Split Formula	Split Result2	Split Result3	Split Result4
YYYY Month Corporate Word1 Word2	Month	Word1	Word2
YYYY Month Corporate Word1 Word2 Word3	Month	Word1	Word2	Word3
YYYY Month Word1 Word2	Month	Word1	Word2
YYYY Month Word1 Word2 Word3	Month	Word1	Word2	Word3

Answer 1

Try this out:

=ARRAYFORMULA(
   IFERROR(
     SPLIT(REGEXREPLACE(A2:A, "\d{4}|Corporate", ), " ")
   )
 )
