Fill in each of the ten labeled boxes in the grid below with a different digit from 0 to 9 to 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 the grid so that the following statements are true?

1. Each digit from 0 to 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 prime numbers is the sum of two others.

Please send in you answer in the following format:
A =
B =
C =
D =
E =
F =
G =
H =
I =
J =

Solution to the Problem:

				5
			4	3
		6	0
	2	7	1
8	9

Now continue to solve, making use of the following facts:
B, D, E, and I must be odd numbers (evens would create more numbers that are not prime).
The number 5 can not be placed in these boxes because it would create another non-prime number.
Hence, boxes B, D, E, and I must contain 1, 3, 7, and 9 (not in that order).
Clue #4 tells us that one prime number is the sum of two other numbers. The other two numbers can not both be prime because the sum of two numbers ending in an odd digit would be even and therefore, not prime. So, the number located in boxes F and G must be added to one of the primes to form a larger prime. Since the composite number ends in zero, you need two primes that end in the same odd digit.
60 + 29 = 89.
