Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028454, here are decompositions:

17 + 1028437 = 1028454
43 + 1028411 = 1028454
61 + 1028393 = 1028454
127 + 1028327 = 1028454
137 + 1028317 = 1028454
151 + 1028303 = 1028454
181 + 1028273 = 1028454
191 + 1028263 = 1028454

Showing the first eight; more decompositions exist.
