Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1040238, here are decompositions:

11 + 1040227 = 1040238
19 + 1040219 = 1040238
47 + 1040191 = 1040238
71 + 1040167 = 1040238
79 + 1040159 = 1040238
97 + 1040141 = 1040238
137 + 1040101 = 1040238
149 + 1040089 = 1040238

Showing the first eight; more decompositions exist.
