SHIKAKU HELP

All prime numbers are contained in a 1x rectangle.  Prime numbers are 2, 3, 5, 7, 11, 13, 17 etc. 

Odd numbers cannot be in a 2x rectangle (Example: 9 = 1x9 or 3x3). 

Anytime you have a number beside another number, you know that they are contained in different areas, therefore you know that a line goes between them.  This is shown with the 3 and 4 in the sample puzzle below.
