Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1030812, here are decompositions:

11 + 1030801 = 1030812
19 + 1030793 = 1030812
53 + 1030759 = 1030812
61 + 1030751 = 1030812
71 + 1030741 = 1030812
73 + 1030739 = 1030812
89 + 1030723 = 1030812
109 + 1030703 = 1030812

Showing the first eight; more decompositions exist.
