Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028558, here are decompositions:

79 + 1028479 = 1028558
229 + 1028329 = 1028558
241 + 1028317 = 1028558
337 + 1028221 = 1028558
367 + 1028191 = 1028558
409 + 1028149 = 1028558
457 + 1028101 = 1028558
541 + 1028017 = 1028558

Showing the first eight; more decompositions exist.
