Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945906, here are decompositions:

7 + 945899 = 945906
19 + 945887 = 945906
23 + 945883 = 945906
83 + 945823 = 945906
89 + 945817 = 945906
97 + 945809 = 945906
107 + 945799 = 945906
139 + 945767 = 945906

Showing the first eight; more decompositions exist.
