Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945918, here are decompositions:

11 + 945907 = 945918
19 + 945899 = 945918
31 + 945887 = 945918
37 + 945881 = 945918
67 + 945851 = 945918
101 + 945817 = 945918
107 + 945811 = 945918
109 + 945809 = 945918

Showing the first eight; more decompositions exist.
