Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666956, here are decompositions:

3 + 8666953 = 8666956
17 + 8666939 = 8666956
29 + 8666927 = 8666956
107 + 8666849 = 8666956
149 + 8666807 = 8666956
173 + 8666783 = 8666956
359 + 8666597 = 8666956
443 + 8666513 = 8666956

Showing the first eight; more decompositions exist.
