Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009628, here are decompositions:

7 + 1009621 = 1009628
19 + 1009609 = 1009628
97 + 1009531 = 1009628
127 + 1009501 = 1009628
211 + 1009417 = 1009628
229 + 1009399 = 1009628
241 + 1009387 = 1009628
271 + 1009357 = 1009628

Showing the first eight; more decompositions exist.
