COMMENTS

There are interesting large jumps within the sequence (e.g., more than doubling from 487 to 1457).
There appears to be the same number of even terms aa odd terms in the sequence.

EXAMPLE

10 is not in the list, as it is 7+3, both odd terms.
66 is not in the list, as it is 50+14+2, all even terms.
38 is in the list since it cannot be represented as the sum of all even terms or all odd terms.
