Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042240, here are decompositions:

29 + 1042211 = 1042240
47 + 1042193 = 1042240
53 + 1042187 = 1042240
107 + 1042133 = 1042240
131 + 1042109 = 1042240
137 + 1042103 = 1042240
149 + 1042091 = 1042240
197 + 1042043 = 1042240

Showing the first eight; more decompositions exist.
