%N Positive even integers that are not the sum of two nonprime odd integers.

%C See A118081 for numbers not representable as the sum of two odd composite numbers. Roberts shows that every even number greater than 38 is the sum of an odd composite number and one of the five composite numbers 9, 15, 21, 27, 33. - _T. D. Noe_, Jun 01 2008, Jun 05 2008
