Yes, I thought to wait until it's verified before posting here, took some time.
Base 290 is the first without a prime on the Kynea (+1) side so that's why I'm searching here but found 'only' one on the Carol side. Altough it's now the biggest prime of such format. C.Caldwells database do not support the naming of "Carol/Kynea" in official so only the clean entry. Base 362 is the one without and prime on the Carol side so searching that base, too.
