Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1049490, here are decompositions:

7 + 1049483 = 1049490
11 + 1049479 = 1049490
17 + 1049473 = 1049490
19 + 1049471 = 1049490
31 + 1049459 = 1049490
53 + 1049437 = 1049490
61 + 1049429 = 1049490
103 + 1049387 = 1049490

Showing the first eight; more decompositions exist.
