Double Goldbach plus epsilon conjecture

Let nn be a positive even integer. A pair of Goldbach representations consists of primes q1,q2,q4,q5q_1,q_2,q_4,q_5 satisfying

q4<q1q2<q5<nq_4<q_1\leqslant q_2<q_5<n

and

q1+q2=q4+q5=n.q_1+q_2=q_4+q_5=n.

There is also a prime q3q_3 with q5<q3<nq_5<q_3<n. Double Goldbach plus ε\varepsilon conjecture. Every positive even integer nn admits primes q1,q2,q3,q4,q5q_1,q_2,q_3,q_4,q_5 such that

q4<q1q2<q5<q3<nq_4<q_1\leqslant q_2<q_5<q_3<n

and

q1+q2=q4+q5=n.q_1+q_2=q_4+q_5=n.

This strengthens Goldbach-type assertions by requiring two ordered representations of the same even integer together with an additional intervening prime; the source provides no resolution.
