Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1041220, here are decompositions:

17 + 1041203 = 1041220
53 + 1041167 = 1041220
71 + 1041149 = 1041220
83 + 1041137 = 1041220
101 + 1041119 = 1041220
137 + 1041083 = 1041220
179 + 1041041 = 1041220
239 + 1040981 = 1041220

Showing the first eight; more decompositions exist.
