COMMENTS
14322 = 2*3*7*11*31.
All terms are multiples of a(1) = 30.
For these numbers numerator(B_{k}) mod denominator(B_{k}) = 12899.

EXAMPLE
Bernoulli B_{30} is 8615841276005/14322, hence 30 is in the sequence.
MAPLE
with(numtheory): P:=proc(q, h) local n; for n from 2 by 2 to q do

# Alternative: # according to Robert Israel code in A282773
with(numtheory): filter:= n ->
