Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1038220, here are decompositions:

11 + 1038209 = 1038220
17 + 1038203 = 1038220
101 + 1038119 = 1038220
173 + 1038047 = 1038220
179 + 1038041 = 1038220
191 + 1038029 = 1038220
257 + 1037963 = 1038220
263 + 1037957 = 1038220

Showing the first eight; more decompositions exist.
