Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945988, here are decompositions:

5 + 945983 = 945988
47 + 945941 = 945988
59 + 945929 = 945988
89 + 945899 = 945988
101 + 945887 = 945988
107 + 945881 = 945988
137 + 945851 = 945988
179 + 945809 = 945988

Showing the first eight; more decompositions exist.
