Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28554, here are decompositions:

5 + 28549 = 28554
7 + 28547 = 28554
13 + 28541 = 28554
17 + 28537 = 28554
37 + 28517 = 28554
41 + 28513 = 28554
61 + 28493 = 28554
107 + 28447 = 28554

Showing the first eight; more decompositions exist.
