Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1040788, here are decompositions:

5 + 1040783 = 1040788
11 + 1040777 = 1040788
17 + 1040771 = 1040788
41 + 1040747 = 1040788
71 + 1040717 = 1040788
131 + 1040657 = 1040788
137 + 1040651 = 1040788
191 + 1040597 = 1040788

Showing the first eight; more decompositions exist.
