Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005664, here are decompositions:

3 + 1005661 = 1005664
17 + 1005647 = 1005664
47 + 1005617 = 1005664
71 + 1005593 = 1005664
83 + 1005581 = 1005664
113 + 1005551 = 1005664
137 + 1005527 = 1005664
197 + 1005467 = 1005664

Showing the first eight; more decompositions exist.
