Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1048640, here are decompositions:

7 + 1048633 = 1048640
13 + 1048627 = 1048640
31 + 1048609 = 1048640
67 + 1048573 = 1048640
193 + 1048447 = 1048640
283 + 1048357 = 1048640
331 + 1048309 = 1048640
349 + 1048291 = 1048640

Showing the first eight; more decompositions exist.
