Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 969820, here are decompositions:

11 + 969809 = 969820
23 + 969797 = 969820
29 + 969791 = 969820
53 + 969767 = 969820
101 + 969719 = 969820
107 + 969713 = 969820
149 + 969671 = 969820
179 + 969641 = 969820

Showing the first eight; more decompositions exist.
