Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005568, here are decompositions:

17 + 1005551 = 1005568
41 + 1005527 = 1005568
101 + 1005467 = 1005568
131 + 1005437 = 1005568
197 + 1005371 = 1005568
251 + 1005317 = 1005568
281 + 1005287 = 1005568
359 + 1005209 = 1005568

Showing the first eight; more decompositions exist.
