Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009398, here are decompositions:

11 + 1009387 = 1009398
29 + 1009369 = 1009398
37 + 1009361 = 1009398
41 + 1009357 = 1009398
79 + 1009319 = 1009398
97 + 1009301 = 1009398
107 + 1009291 = 1009398
109 + 1009289 = 1009398

Showing the first eight; more decompositions exist.
