Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###
TABLE: CREATE TABLE table_42565 ( "1861" real, "1866" real, "1872" real, "1876" real, "1881" real, "1886" real, "1891" real )

### Question ###
What is the sum of 1872(s), when 1866 is greater than 856, when 1861 is greater than 1906, and when 1876 is greater than 1990?

### Accurate SQL ###

SELECT SUM("1872") FROM table_42565 WHERE "1866" > '856' AND "1861" > '1906' AND "1876" > '1990'
