Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009870, here are decompositions:

11 + 1009859 = 1009870
83 + 1009787 = 1009870
89 + 1009781 = 1009870
227 + 1009643 = 1009870
233 + 1009637 = 1009870
269 + 1009601 = 1009870
311 + 1009559 = 1009870
383 + 1009487 = 1009870

Showing the first eight; more decompositions exist.
