Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042278, here are decompositions:

5 + 1042273 = 1042278
7 + 1042271 = 1042278
11 + 1042267 = 1042278
19 + 1042259 = 1042278
37 + 1042241 = 1042278
67 + 1042211 = 1042278
137 + 1042141 = 1042278
157 + 1042121 = 1042278

Showing the first eight; more decompositions exist.
