Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009450, here are decompositions:

11 + 1009439 = 1009450
17 + 1009433 = 1009450
89 + 1009361 = 1009450
107 + 1009343 = 1009450
131 + 1009319 = 1009450
149 + 1009301 = 1009450
191 + 1009259 = 1009450
251 + 1009199 = 1009450

Showing the first eight; more decompositions exist.
