Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005564, here are decompositions:

11 + 1005553 = 1005564
13 + 1005551 = 1005564
23 + 1005541 = 1005564
37 + 1005527 = 1005564
61 + 1005503 = 1005564
71 + 1005493 = 1005564
83 + 1005481 = 1005564
97 + 1005467 = 1005564

Showing the first eight; more decompositions exist.
