Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1038238, here are decompositions:

11 + 1038227 = 1038238
29 + 1038209 = 1038238
191 + 1038047 = 1038238
197 + 1038041 = 1038238
281 + 1037957 = 1038238
359 + 1037879 = 1038238
419 + 1037819 = 1038238
479 + 1037759 = 1038238

Showing the first eight; more decompositions exist.
