Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27428, here are decompositions:

19 + 27409 = 27428
31 + 27397 = 27428
61 + 27367 = 27428
67 + 27361 = 27428
151 + 27277 = 27428
157 + 27271 = 27428
337 + 27091 = 27428
367 + 27061 = 27428

Showing the first eight; more decompositions exist.
