Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019580, here are decompositions:

17 + 1019563 = 1019580
31 + 1019549 = 1019580
43 + 1019537 = 1019580
47 + 1019533 = 1019580
71 + 1019509 = 1019580
101 + 1019479 = 1019580
109 + 1019471 = 1019580
113 + 1019467 = 1019580

Showing the first eight; more decompositions exist.
