The submitted version is so far off the corrected version that
I tested alternatives of the definition like
(i) interpreting the sequence as the intersection
of A134651 and A001043, (no match with the submission)
(ii) interpreting the sequence as those terms where the sum is kind of
(iii) allowing only sums of two terms but disallowing numbers that could

The challenge is to find the answer to the question:
what defines A135045 really?
