Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945930, here are decompositions:

23 + 945907 = 945930
31 + 945899 = 945930
43 + 945887 = 945930
47 + 945883 = 945930
79 + 945851 = 945930
107 + 945823 = 945930
113 + 945817 = 945930
131 + 945799 = 945930

Showing the first eight; more decompositions exist.
