Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28552, here are decompositions:

3 + 28549 = 28552
5 + 28547 = 28552
11 + 28541 = 28552
53 + 28499 = 28552
59 + 28493 = 28552
89 + 28463 = 28552
113 + 28439 = 28552
149 + 28403 = 28552

Showing the first eight; more decompositions exist.
