Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042438, here are decompositions:

11 + 1042427 = 1042438
107 + 1042331 = 1042438
167 + 1042271 = 1042438
179 + 1042259 = 1042438
197 + 1042241 = 1042438
227 + 1042211 = 1042438
251 + 1042187 = 1042438
317 + 1042121 = 1042438

Showing the first eight; more decompositions exist.
