Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028582, here are decompositions:

3 + 1028579 = 1028582
13 + 1028569 = 1028582
73 + 1028509 = 1028582
103 + 1028479 = 1028582
109 + 1028473 = 1028582
193 + 1028389 = 1028582
433 + 1028149 = 1028582
571 + 1028011 = 1028582

Showing the first eight; more decompositions exist.
