Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020396, here are decompositions:

7 + 1020389 = 1020396
17 + 1020379 = 1020396
43 + 1020353 = 1020396
59 + 1020337 = 1020396
67 + 1020329 = 1020396
103 + 1020293 = 1020396
127 + 1020269 = 1020396
137 + 1020259 = 1020396

Showing the first eight; more decompositions exist.
