Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28582, here are decompositions:

3 + 28579 = 28582
11 + 28571 = 28582
23 + 28559 = 28582
41 + 28541 = 28582
83 + 28499 = 28582
89 + 28493 = 28582
149 + 28433 = 28582
173 + 28409 = 28582

Showing the first eight; more decompositions exist.
