Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1040438, here are decompositions:

19 + 1040419 = 1040438
31 + 1040407 = 1040438
67 + 1040371 = 1040438
127 + 1040311 = 1040438
211 + 1040227 = 1040438
271 + 1040167 = 1040438
277 + 1040161 = 1040438
337 + 1040101 = 1040438

Showing the first eight; more decompositions exist.
