Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005426, here are decompositions:

13 + 1005413 = 1005426
17 + 1005409 = 1005426
53 + 1005373 = 1005426
67 + 1005359 = 1005426
109 + 1005317 = 1005426
113 + 1005313 = 1005426
139 + 1005287 = 1005426
157 + 1005269 = 1005426

Showing the first eight; more decompositions exist.
