Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019550, here are decompositions:

13 + 1019537 = 1019550
17 + 1019533 = 1019550
19 + 1019531 = 1019550
41 + 1019509 = 1019550
47 + 1019503 = 1019550
71 + 1019479 = 1019550
79 + 1019471 = 1019550
83 + 1019467 = 1019550

Showing the first eight; more decompositions exist.
