Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8745166, here are decompositions:

5 + 8745161 = 8745166
47 + 8745119 = 8745166
149 + 8745017 = 8745166
197 + 8744969 = 8745166
239 + 8744927 = 8745166
257 + 8744909 = 8745166
263 + 8744903 = 8745166
347 + 8744819 = 8745166

Showing the first eight; more decompositions exist.
