Not sure I understand the question here. It seems to me it is pointless considering any numbers greater than eighteen (18 + 1 = 19) so the limit of a million says to me that the question might not be what it appears to be. If the question is how many positive numbers in groups of any size add up to 19 I'll think about it.
