Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8745966, here are decompositions:

37 + 8745929 = 8745966
43 + 8745923 = 8745966
109 + 8745857 = 8745966
137 + 8745829 = 8745966
139 + 8745827 = 8745966
149 + 8745817 = 8745966
167 + 8745799 = 8745966
199 + 8745767 = 8745966

Showing the first eight; more decompositions exist.
