Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005678, here are decompositions:

17 + 1005661 = 1005678
31 + 1005647 = 1005678
41 + 1005637 = 1005678
59 + 1005619 = 1005678
61 + 1005617 = 1005678
97 + 1005581 = 1005678
127 + 1005551 = 1005678
137 + 1005541 = 1005678

Showing the first eight; more decompositions exist.
