Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009388, here are decompositions:

19 + 1009369 = 1009388
31 + 1009357 = 1009388
67 + 1009321 = 1009388
97 + 1009291 = 1009388
151 + 1009237 = 1009388
181 + 1009207 = 1009388
199 + 1009189 = 1009388
229 + 1009159 = 1009388

Showing the first eight; more decompositions exist.
