Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27378, here are decompositions:

11 + 27367 = 27378
17 + 27361 = 27378
41 + 27337 = 27378
79 + 27299 = 27378
97 + 27281 = 27378
101 + 27277 = 27378
107 + 27271 = 27378
137 + 27241 = 27378

Showing the first eight; more decompositions exist.
