Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008256, here are decompositions:

17 + 1008239 = 1008256
23 + 1008233 = 1008256
47 + 1008209 = 1008256
239 + 1008017 = 1008256
317 + 1007939 = 1008256
383 + 1007873 = 1008256
443 + 1007813 = 1008256
449 + 1007807 = 1008256

Showing the first eight; more decompositions exist.
