Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018450, here are decompositions:

3 + 1018447 = 1018450
11 + 1018439 = 1018450
29 + 1018421 = 1018450
113 + 1018337 = 1018450
137 + 1018313 = 1018450
149 + 1018301 = 1018450
179 + 1018271 = 1018450
197 + 1018253 = 1018450

Showing the first eight; more decompositions exist.
