Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005570, here are decompositions:

17 + 1005553 = 1005570
19 + 1005551 = 1005570
29 + 1005541 = 1005570
43 + 1005527 = 1005570
67 + 1005503 = 1005570
89 + 1005481 = 1005570
103 + 1005467 = 1005570
113 + 1005457 = 1005570

Showing the first eight; more decompositions exist.
