split ARGB into byte values

I have a ARGB value stored as an int type. It was stored by calling ToArgb.

I now want the byte values of the individual color channels from the int value.

for example

int mycolor = -16744448;
byte r,g,b,a;

GetBytesFromColor(mycolor,out a, out r, out g, out b);

How would you implement GetBytesFromColor?

To give the context I am passing a color value persisted in db as int to a silverlight application which needs the individual byte values to construct a color object.

System.Windows.Media.Color.FromArgb(byte a, byte r, byte g, byte b)
