COMMENTS

For odious-evil partition of positive integers, see A000069, A001969; for odious-evil partition of relatively prime to n numbers <=n, see A230070, A230120.

Since Euler totient sequence A000010 takes only even values, then for some of them we have a representations as a sum of two primes.
