Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009208, here are decompositions:

7 + 1009201 = 1009208
19 + 1009189 = 1009208
229 + 1008979 = 1009208
271 + 1008937 = 1009208
307 + 1008901 = 1009208
337 + 1008871 = 1009208
349 + 1008859 = 1009208
379 + 1008829 = 1009208

Showing the first eight; more decompositions exist.
