Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1029440, here are decompositions:

7 + 1029433 = 1029440
31 + 1029409 = 1029440
37 + 1029403 = 1029440
79 + 1029361 = 1029440
103 + 1029337 = 1029440
109 + 1029331 = 1029440
151 + 1029289 = 1029440
163 + 1029277 = 1029440

Showing the first eight; more decompositions exist.
