Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1049540, here are decompositions:

3 + 1049537 = 1049540
7 + 1049533 = 1049540
13 + 1049527 = 1049540
31 + 1049509 = 1049540
43 + 1049497 = 1049540
61 + 1049479 = 1049540
67 + 1049473 = 1049540
103 + 1049437 = 1049540

Showing the first eight; more decompositions exist.
