Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28522, here are decompositions:

5 + 28517 = 28522
23 + 28499 = 28522
29 + 28493 = 28522
59 + 28463 = 28522
83 + 28439 = 28522
89 + 28433 = 28522
113 + 28409 = 28522
173 + 28349 = 28522

Showing the first eight; more decompositions exist.
