Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 965820, here are decompositions:

19 + 965801 = 965820
29 + 965791 = 965820
41 + 965779 = 965820
43 + 965777 = 965820
47 + 965773 = 965820
61 + 965759 = 965820
71 + 965749 = 965820
109 + 965711 = 965820

Showing the first eight; more decompositions exist.
