Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 969640, here are decompositions:

3 + 969637 = 969640
41 + 969599 = 969640
47 + 969593 = 969640
71 + 969569 = 969640
107 + 969533 = 969640
131 + 969509 = 969640
137 + 969503 = 969640
173 + 969467 = 969640

Showing the first eight; more decompositions exist.
