Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1012788, here are decompositions:

17 + 1012771 = 1012788
19 + 1012769 = 1012788
37 + 1012751 = 1012788
67 + 1012721 = 1012788
71 + 1012717 = 1012788
89 + 1012699 = 1012788
97 + 1012691 = 1012788
109 + 1012679 = 1012788

Showing the first eight; more decompositions exist.
