Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27520, here are decompositions:

11 + 27509 = 27520
41 + 27479 = 27520
71 + 27449 = 27520
83 + 27437 = 27520
89 + 27431 = 27520
113 + 27407 = 27520
191 + 27329 = 27520
239 + 27281 = 27520

Showing the first eight; more decompositions exist.
