Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1038388, here are decompositions:

5 + 1038383 = 1038388
59 + 1038329 = 1038388
137 + 1038251 = 1038388
179 + 1038209 = 1038388
269 + 1038119 = 1038388
311 + 1038077 = 1038388
347 + 1038041 = 1038388
359 + 1038029 = 1038388

Showing the first eight; more decompositions exist.
