Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009220, here are decompositions:

13 + 1009207 = 1009220
19 + 1009201 = 1009220
31 + 1009189 = 1009220
61 + 1009159 = 1009220
67 + 1009153 = 1009220
229 + 1008991 = 1009220
241 + 1008979 = 1009220
283 + 1008937 = 1009220

Showing the first eight; more decompositions exist.
