Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020408, here are decompositions:

7 + 1020401 = 1020408
19 + 1020389 = 1020408
29 + 1020379 = 1020408
47 + 1020361 = 1020408
71 + 1020337 = 1020408
79 + 1020329 = 1020408
107 + 1020301 = 1020408
139 + 1020269 = 1020408

Showing the first eight; more decompositions exist.
