Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009406, here are decompositions:

7 + 1009399 = 1009406
19 + 1009387 = 1009406
37 + 1009369 = 1009406
103 + 1009303 = 1009406
163 + 1009243 = 1009406
199 + 1009207 = 1009406
547 + 1008859 = 1009406
577 + 1008829 = 1009406

Showing the first eight; more decompositions exist.
