Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1024638, here are decompositions:

5 + 1024633 = 1024638
29 + 1024609 = 1024638
47 + 1024591 = 1024638
59 + 1024579 = 1024638
61 + 1024577 = 1024638
79 + 1024559 = 1024638
127 + 1024511 = 1024638
157 + 1024481 = 1024638

Showing the first eight; more decompositions exist.
