Default Excel Addition Error

Perhaps the "somewhere else" may have non-integers formatted as integer?

is it just paste, or paste special?

I also get 4,496,180.

How about formatting those cells to sum as General and widening the
column.
Maybe some of the decimal portions are hidden (by format or by column
width).

Open an Excel spreadsheet, format a column as numeric, no decimals, and

1,477,789

130,714
84,053
524,606
1,724,962
93,586

Sum them. You will get the answer 4,496,179. The correct answer is
4,496,180. I would suggest you incorporate round-off error correction
routines in your math calculations. This is strictly a newbie error, and
I'm
frankly amazed that you haven't caught it yet.
