Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1038580, here are decompositions:

17 + 1038563 = 1038580
41 + 1038539 = 1038580
83 + 1038497 = 1038580
131 + 1038449 = 1038580
197 + 1038383 = 1038580
251 + 1038329 = 1038580
269 + 1038311 = 1038580
311 + 1038269 = 1038580

Showing the first eight; more decompositions exist.
