Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009906, here are decompositions:

5 + 1009901 = 1009906
47 + 1009859 = 1009906
179 + 1009727 = 1009906
257 + 1009649 = 1009906
263 + 1009643 = 1009906
269 + 1009637 = 1009906
347 + 1009559 = 1009906
419 + 1009487 = 1009906

Showing the first eight; more decompositions exist.
