Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031640, here are decompositions:

7 + 1031633 = 1031640
11 + 1031629 = 1031640
17 + 1031623 = 1031640
31 + 1031609 = 1031640
47 + 1031593 = 1031640
79 + 1031561 = 1031640
107 + 1031533 = 1031640
109 + 1031531 = 1031640

Showing the first eight; more decompositions exist.
