Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1048638, here are decompositions:

5 + 1048633 = 1048638
11 + 1048627 = 1048638
29 + 1048609 = 1048638
37 + 1048601 = 1048638
67 + 1048571 = 1048638
79 + 1048559 = 1048638
89 + 1048549 = 1048638
131 + 1048507 = 1048638

Showing the first eight; more decompositions exist.
