Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005628, here are decompositions:

11 + 1005617 = 1005628
47 + 1005581 = 1005628
101 + 1005527 = 1005628
191 + 1005437 = 1005628
257 + 1005371 = 1005628
269 + 1005359 = 1005628
311 + 1005317 = 1005628
359 + 1005269 = 1005628

Showing the first eight; more decompositions exist.
