Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945940, here are decompositions:

3 + 945937 = 945940
11 + 945929 = 945940
41 + 945899 = 945940
53 + 945887 = 945940
59 + 945881 = 945940
89 + 945851 = 945940
131 + 945809 = 945940
173 + 945767 = 945940

Showing the first eight; more decompositions exist.
