Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27438, here are decompositions:

7 + 27431 = 27438
11 + 27427 = 27438
29 + 27409 = 27438
31 + 27407 = 27438
41 + 27397 = 27438
71 + 27367 = 27438
101 + 27337 = 27438
109 + 27329 = 27438

Showing the first eight; more decompositions exist.
