Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1038320, here are decompositions:

13 + 1038307 = 1038320
61 + 1038259 = 1038320
67 + 1038253 = 1038320
109 + 1038211 = 1038320
163 + 1038157 = 1038320
193 + 1038127 = 1038320
277 + 1038043 = 1038320
337 + 1037983 = 1038320

Showing the first eight; more decompositions exist.
