Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045638, here are decompositions:

5 + 1045633 = 1045638
17 + 1045621 = 1045638
31 + 1045607 = 1045638
67 + 1045571 = 1045638
79 + 1045559 = 1045638
89 + 1045549 = 1045638
109 + 1045529 = 1045638
131 + 1045507 = 1045638

Showing the first eight; more decompositions exist.
