Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 936820, here are decompositions:

23 + 936797 = 936820
41 + 936779 = 936820
47 + 936773 = 936820
83 + 936737 = 936820
89 + 936731 = 936820
107 + 936713 = 936820
173 + 936647 = 936820
233 + 936587 = 936820

Showing the first eight; more decompositions exist.
