return field name and number of rows which meet condition in one sentence

I have a table in postgres with 10 fields, and need to check for certain values in 3 of them, then return the field name which met the condition and the number of rows in each field. So it's something like:

select count(*)
from table
where field1 ilike '%E+%'
OR field2 ilike '%E+%'
OR field3 ilike '%E+%'

and then return the field which met the condition AND the number of rows (which I'm not sure how to do it)
