Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28564, here are decompositions:

5 + 28559 = 28564
17 + 28547 = 28564
23 + 28541 = 28564
47 + 28517 = 28564
71 + 28493 = 28564
101 + 28463 = 28564
131 + 28433 = 28564
257 + 28307 = 28564

Showing the first eight; more decompositions exist.
