Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1027438, here are decompositions:

11 + 1027427 = 1027438
17 + 1027421 = 1027438
29 + 1027409 = 1027438
47 + 1027391 = 1027438
107 + 1027331 = 1027438
149 + 1027289 = 1027438
197 + 1027241 = 1027438
227 + 1027211 = 1027438

Showing the first eight; more decompositions exist.
