Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028358, here are decompositions:

29 + 1028329 = 1028358
31 + 1028327 = 1028358
41 + 1028317 = 1028358
127 + 1028231 = 1028358
137 + 1028221 = 1028358
151 + 1028207 = 1028358
157 + 1028201 = 1028358
167 + 1028191 = 1028358

Showing the first eight; more decompositions exist.
