1919190 = 2*3*5*7*13*19*37.
All terms are multiples of a(1) = 36.
For these numbers numerator(B_{k}) mod denominator(B_{k}) = 1280537.

EXAMPLE
Bernoulli B_{36} is
-26315271553053477373/1919190, hence 36 is in the sequence.

# Alternative according to Robert Israel's code in A282773:

select(filter, [seq(i, i=1..10^5)]);
