Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028448, here are decompositions:

11 + 1028437 = 1028448
37 + 1028411 = 1028448
59 + 1028389 = 1028448
131 + 1028317 = 1028448
139 + 1028309 = 1028448
227 + 1028221 = 1028448
241 + 1028207 = 1028448
257 + 1028191 = 1028448

Showing the first eight; more decompositions exist.
