Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1040920, here are decompositions:

29 + 1040891 = 1040920
47 + 1040873 = 1040920
59 + 1040861 = 1040920
107 + 1040813 = 1040920
113 + 1040807 = 1040920
137 + 1040783 = 1040920
149 + 1040771 = 1040920
173 + 1040747 = 1040920

Showing the first eight; more decompositions exist.
