Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019540, here are decompositions:

3 + 1019537 = 1019540
7 + 1019533 = 1019540
31 + 1019509 = 1019540
37 + 1019503 = 1019540
61 + 1019479 = 1019540
73 + 1019467 = 1019540
97 + 1019443 = 1019540
127 + 1019413 = 1019540

Showing the first eight; more decompositions exist.
