Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019522, here are decompositions:

13 + 1019509 = 1019522
19 + 1019503 = 1019522
43 + 1019479 = 1019522
73 + 1019449 = 1019522
79 + 1019443 = 1019522
109 + 1019413 = 1019522
193 + 1019329 = 1019522
241 + 1019281 = 1019522

Showing the first eight; more decompositions exist.
