Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028532, here are decompositions:

23 + 1028509 = 1028532
53 + 1028479 = 1028532
59 + 1028473 = 1028532
61 + 1028471 = 1028532
139 + 1028393 = 1028532
199 + 1028333 = 1028532
223 + 1028309 = 1028532
229 + 1028303 = 1028532

Showing the first eight; more decompositions exist.
