Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1064640, here are decompositions:

11 + 1064629 = 1064640
47 + 1064593 = 1064640
53 + 1064587 = 1064640
107 + 1064533 = 1064640
163 + 1064477 = 1064640
167 + 1064473 = 1064640
173 + 1064467 = 1064640
229 + 1064411 = 1064640

Showing the first eight; more decompositions exist.
