Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1043640, here are decompositions:

23 + 1043617 = 1043640
41 + 1043599 = 1043640
43 + 1043597 = 1043640
47 + 1043593 = 1043640
53 + 1043587 = 1043640
83 + 1043557 = 1043640
97 + 1043543 = 1043640
109 + 1043531 = 1043640

Showing the first eight; more decompositions exist.
