# Way too Big to Count

Level pendingA marker is placed at the origin in a \(500\)-dimensional coordinate system. The marker has \(1000\) moves, and each move consists of changing one coordinate by exactly 1. Find the **last three digits** of the number of ways the marker can get to a point that is at least \(500\) units away from the origin.

**Details and assumptions**

The marker has no restrictions on movement, it can move in any direction, forwards or backwards along any axis any time.

The marker can end with any nonnegative number of moves remaining.

The marker is **forced** to stop if it reaches a point at least \(500\) units away from the origin.
