Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27556, here are decompositions:

5 + 27551 = 27556
17 + 27539 = 27556
29 + 27527 = 27556
47 + 27509 = 27556
107 + 27449 = 27556
149 + 27407 = 27556
227 + 27329 = 27556
257 + 27299 = 27556

Showing the first eight; more decompositions exist.
