Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028562, here are decompositions:

5 + 1028557 = 1028562
53 + 1028509 = 1028562
83 + 1028479 = 1028562
89 + 1028473 = 1028562
151 + 1028411 = 1028562
173 + 1028389 = 1028562
229 + 1028333 = 1028562
233 + 1028329 = 1028562

Showing the first eight; more decompositions exist.
