I have a column with a large number (more than 14 digits) And everytime there is a number this large we would like to duplicate this row and subtract a fixed value from this column. Let's say the original number is 12345678942354, I want to subtract 9999999999999 from it, and create a new row where the original row would contain the result of this operation, and the second row would contain the rest. When we sum this 2 rows the result would be 12345678942354. Is it possible?
