Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945864, here are decompositions:

13 + 945851 = 945864
41 + 945823 = 945864
47 + 945817 = 945864
53 + 945811 = 945864
97 + 945767 = 945864
131 + 945733 = 945864
163 + 945701 = 945864
191 + 945673 = 945864

Showing the first eight; more decompositions exist.
