Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009438, here are decompositions:

5 + 1009433 = 1009438
137 + 1009301 = 1009438
149 + 1009289 = 1009438
179 + 1009259 = 1009438
191 + 1009247 = 1009438
239 + 1009199 = 1009438
281 + 1009157 = 1009438
317 + 1009121 = 1009438

Showing the first eight; more decompositions exist.
