Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945828, here are decompositions:

5 + 945823 = 945828
11 + 945817 = 945828
17 + 945811 = 945828
19 + 945809 = 945828
29 + 945799 = 945828
41 + 945787 = 945828
61 + 945767 = 945828
89 + 945739 = 945828

Showing the first eight; more decompositions exist.
