Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 969840, here are decompositions:

19 + 969821 = 969840
31 + 969809 = 969840
43 + 969797 = 969840
73 + 969767 = 969840
83 + 969757 = 969840
97 + 969743 = 969840
127 + 969713 = 969840
163 + 969677 = 969840

Showing the first eight; more decompositions exist.
