Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025664, here are decompositions:

5 + 1025659 = 1025664
11 + 1025653 = 1025664
23 + 1025641 = 1025664
41 + 1025623 = 1025664
43 + 1025621 = 1025664
53 + 1025611 = 1025664
103 + 1025561 = 1025664
113 + 1025551 = 1025664

Showing the first eight; more decompositions exist.
