Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8673966, here are decompositions:

13 + 8673953 = 8673966
43 + 8673923 = 8673966
53 + 8673913 = 8673966
89 + 8673877 = 8673966
127 + 8673839 = 8673966
149 + 8673817 = 8673966
239 + 8673727 = 8673966
263 + 8673703 = 8673966

Showing the first eight; more decompositions exist.
