Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1038628, here are decompositions:

5 + 1038623 = 1038628
11 + 1038617 = 1038628
29 + 1038599 = 1038628
89 + 1038539 = 1038628
131 + 1038497 = 1038628
179 + 1038449 = 1038628
317 + 1038311 = 1038628
359 + 1038269 = 1038628

Showing the first eight; more decompositions exist.
