Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005630, here are decompositions:

11 + 1005619 = 1005630
13 + 1005617 = 1005630
37 + 1005593 = 1005630
79 + 1005551 = 1005630
89 + 1005541 = 1005630
103 + 1005527 = 1005630
127 + 1005503 = 1005630
137 + 1005493 = 1005630

Showing the first eight; more decompositions exist.
