Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709966, here are decompositions:

7 + 8709959 = 8709966
37 + 8709929 = 8709966
47 + 8709919 = 8709966
53 + 8709913 = 8709966
127 + 8709839 = 8709966
149 + 8709817 = 8709966
173 + 8709793 = 8709966
229 + 8709737 = 8709966

Showing the first eight; more decompositions exist.
