Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028554, here are decompositions:

83 + 1028471 = 1028554
227 + 1028327 = 1028554
251 + 1028303 = 1028554
281 + 1028273 = 1028554
311 + 1028243 = 1028554
347 + 1028207 = 1028554
353 + 1028201 = 1028554
491 + 1028063 = 1028554

Showing the first eight; more decompositions exist.
