Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666996, here are decompositions:

3 + 8666993 = 8666996
7 + 8666989 = 8666996
43 + 8666953 = 8666996
157 + 8666839 = 8666996
199 + 8666797 = 8666996
223 + 8666773 = 8666996
229 + 8666767 = 8666996
313 + 8666683 = 8666996

Showing the first eight; more decompositions exist.
