advertising the recent revival of a couple of (related) factorization projects I had previously overlooked:
Sam Wagstaff (of Cunningham project fame) leads an initiative to find factors of Bernoulli, and Euler composites at:

Note that Bruce Dodson has already found some good-sized ECM factors from these targets, presumably as a diversion from the main Cunningham project!
Some links describing these numbers:
