COMMENTS
We conjecture that the sequence is infinite. This sequence shows the proximity of A284919 and A277688 based on Goldbach and Lemoine-Levy representations of even and odd numbers respectively.
The differences between the positions of the corresponding terms of A284919 and A277688 are 0,0,0,1,0,2,2,1,1,1,2,3,2,2,2,2,3,1,... .
The differences between these terms are -1,-1,-1,1,-1,-1,1,1,-1,-1,-1,-1,-1,1,-1,1,1,... .
