Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8582, here are decompositions:

19 + 8563 = 8582
43 + 8539 = 8582
61 + 8521 = 8582
139 + 8443 = 8582
151 + 8431 = 8582
163 + 8419 = 8582
193 + 8389 = 8582
229 + 8353 = 8582

Showing the first eight; more decompositions exist.
