Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27658, here are decompositions:

5 + 27653 = 27658
11 + 27647 = 27658
41 + 27617 = 27658
47 + 27611 = 27658
107 + 27551 = 27658
131 + 27527 = 27658
149 + 27509 = 27658
179 + 27479 = 27658

Showing the first eight; more decompositions exist.
