Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028590, here are decompositions:

11 + 1028579 = 1028590
29 + 1028561 = 1028590
179 + 1028411 = 1028590
197 + 1028393 = 1028590
257 + 1028333 = 1028590
263 + 1028327 = 1028590
281 + 1028309 = 1028590
317 + 1028273 = 1028590

Showing the first eight; more decompositions exist.
