grep with regular expression optional value

field 12345 12345
field 12345
field 12345 123456

last fleld (from three) is optional, but if it occures It has to be composed only of nummbers and maximum 5 positions long.

If I use:

Code:
grep "^field [0-9]\{5\}"

I get:

field 12345 12345
field 12345
field 12345 123456

But I wont to get just:

field 12345 12345
field 12345

I thought that this will work, but it doesent:
Code:
grep "^field [0-9]\{5\} [0-9]\{0,5\}"
