Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1041638, here are decompositions:

19 + 1041619 = 1041638
61 + 1041577 = 1041638
67 + 1041571 = 1041638
79 + 1041559 = 1041638
109 + 1041529 = 1041638
127 + 1041511 = 1041638
211 + 1041427 = 1041638
331 + 1041307 = 1041638

Showing the first eight; more decompositions exist.
