Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27558, here are decompositions:

7 + 27551 = 27558
17 + 27541 = 27558
19 + 27539 = 27558
29 + 27529 = 27558
31 + 27527 = 27558
71 + 27487 = 27558
79 + 27479 = 27558
101 + 27457 = 27558

Showing the first eight; more decompositions exist.
