Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019556, here are decompositions:

7 + 1019549 = 1019556
19 + 1019537 = 1019556
23 + 1019533 = 1019556
47 + 1019509 = 1019556
53 + 1019503 = 1019556
89 + 1019467 = 1019556
103 + 1019453 = 1019556
107 + 1019449 = 1019556

Showing the first eight; more decompositions exist.
