Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009828, here are decompositions:

41 + 1009787 = 1009828
47 + 1009781 = 1009828
101 + 1009727 = 1009828
179 + 1009649 = 1009828
191 + 1009637 = 1009828
227 + 1009601 = 1009828
269 + 1009559 = 1009828
389 + 1009439 = 1009828

Showing the first eight; more decompositions exist.
