Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019516, here are decompositions:

7 + 1019509 = 1019516
13 + 1019503 = 1019516
37 + 1019479 = 1019516
67 + 1019449 = 1019516
73 + 1019443 = 1019516
103 + 1019413 = 1019516
139 + 1019377 = 1019516
163 + 1019353 = 1019516

Showing the first eight; more decompositions exist.
