Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1040880, here are decompositions:

7 + 1040873 = 1040880
19 + 1040861 = 1040880
23 + 1040857 = 1040880
47 + 1040833 = 1040880
53 + 1040827 = 1040880
59 + 1040821 = 1040880
67 + 1040813 = 1040880
73 + 1040807 = 1040880

Showing the first eight; more decompositions exist.
