Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1040830, here are decompositions:

3 + 1040827 = 1040830
17 + 1040813 = 1040830
23 + 1040807 = 1040830
47 + 1040783 = 1040830
53 + 1040777 = 1040830
59 + 1040771 = 1040830
83 + 1040747 = 1040830
113 + 1040717 = 1040830

Showing the first eight; more decompositions exist.
