Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27550, here are decompositions:

11 + 27539 = 27550
23 + 27527 = 27550
41 + 27509 = 27550
71 + 27479 = 27550
101 + 27449 = 27550
113 + 27437 = 27550
251 + 27299 = 27550
269 + 27281 = 27550

Showing the first eight; more decompositions exist.
