To solve this expression, we can simplify each part separately and then combine the results.

First, let's simplify the expression inside the first parentheses: -(-945 + 2567).
-(-945 + 2567) = -(-1578) = 1578.

Next, let's simplify the expression inside the second parentheses: 2567 - 1945.
2567 - 1945 = 622.

Now, we can combine the results:
1578 + 622 = 2200.

Therefore, -(-945+2567)+(2567-1945) equals 2200.
