Redistributing only even subnets.

An interesting issue has arisen.

I'm running OSPF to EIGRP redistribution and want to advertise a group of
class B subnets. 158.168.1.0 through 158.168.92.0. However odd number subnets
need not be advertised. EG. Advertise 158.168.2.0 and 158.168.4.0 through...
but not 158.168.3.0 or 158.168.5.0 etc, etc.

I've been playing with a series of access lists and route maps but is there an
easy way to do it with minimal commands? It seems to me that the last bit in
the third octet is the discriminator between odd and even but I can't seem to
get this to translate to an access-list which works with redistribution.

Thanks,
Cliff.
