Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27480, here are decompositions:

23 + 27457 = 27480
31 + 27449 = 27480
43 + 27437 = 27480
53 + 27427 = 27480
71 + 27409 = 27480
73 + 27407 = 27480
83 + 27397 = 27480
113 + 27367 = 27480

Showing the first eight; more decompositions exist.
