Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28562, here are decompositions:

3 + 28559 = 28562
13 + 28549 = 28562
151 + 28411 = 28562
211 + 28351 = 28562
283 + 28279 = 28562
379 + 28183 = 28562
439 + 28123 = 28562
463 + 28099 = 28562

Showing the first eight; more decompositions exist.
