Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008730, here are decompositions:

11 + 1008719 = 1008730
29 + 1008701 = 1008730
71 + 1008659 = 1008730
113 + 1008617 = 1008730
167 + 1008563 = 1008730
227 + 1008503 = 1008730
263 + 1008467 = 1008730
293 + 1008437 = 1008730

Showing the first eight; more decompositions exist.
