Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27728, here are decompositions:

31 + 27697 = 27728
37 + 27691 = 27728
97 + 27631 = 27728
199 + 27529 = 27728
241 + 27487 = 27728
271 + 27457 = 27728
331 + 27397 = 27728
367 + 27361 = 27728

Showing the first eight; more decompositions exist.
