Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8745066, here are decompositions:

47 + 8745019 = 8745066
97 + 8744969 = 8745066
137 + 8744929 = 8745066
139 + 8744927 = 8745066
149 + 8744917 = 8745066
157 + 8744909 = 8745066
163 + 8744903 = 8745066
179 + 8744887 = 8745066

Showing the first eight; more decompositions exist.
