%N Number of ways of representing n as the sum of one or more consecutive nonprime numbers (A018252).

%e a(2) = 2 because n = 2 itself is already a nonprime number (sum of 1 term), and 1 can in addition be written as A018252(1) + A018252(2), a sum of 2 consecutive nonprime numbers.

%Y Cf. A051349, A053767, A018252, A166037, A166039, A242667, A257393.
