Prime Choices



When you fill in each box in the grid below with a different number from 0 to 9, you will form eight two- and three-digit numbers in the rows and columns (four reading across, and four reading down).

Can you find a way to fill in the grid so that the following statements are all true?

1. Each digit from 0 through 9 is used once.

2. No number begins with 0.

3. Seven of the eight numbers are prime; the number that is not prime reads across.

4. One of the numbers is the sum of two of the others.
