Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028384, here are decompositions:

67 + 1028317 = 1028384
163 + 1028221 = 1028384
193 + 1028191 = 1028384
271 + 1028113 = 1028384
277 + 1028107 = 1028384
283 + 1028101 = 1028384
337 + 1028047 = 1028384
367 + 1028017 = 1028384

Showing the first eight; more decompositions exist.
