Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1040808, here are decompositions:

5 + 1040803 = 1040808
11 + 1040797 = 1040808
29 + 1040779 = 1040808
31 + 1040777 = 1040808
37 + 1040771 = 1040808
59 + 1040749 = 1040808
61 + 1040747 = 1040808
137 + 1040671 = 1040808

Showing the first eight; more decompositions exist.
