Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1040878, here are decompositions:

5 + 1040873 = 1040878
17 + 1040861 = 1040878
71 + 1040807 = 1040878
101 + 1040777 = 1040878
107 + 1040771 = 1040878
131 + 1040747 = 1040878
227 + 1040651 = 1040878
281 + 1040597 = 1040878

Showing the first eight; more decompositions exist.
