Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 969866, here are decompositions:

3 + 969863 = 969866
103 + 969763 = 969866
109 + 969757 = 969866
199 + 969667 = 969866
229 + 969637 = 969866
307 + 969559 = 969866
409 + 969457 = 969866
433 + 969433 = 969866

Showing the first eight; more decompositions exist.
