Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725166, here are decompositions:

7 + 8725159 = 8725166
13 + 8725153 = 8725166
19 + 8725147 = 8725166
67 + 8725099 = 8725166
127 + 8725039 = 8725166
199 + 8724967 = 8725166
223 + 8724943 = 8725166
283 + 8724883 = 8725166

Showing the first eight; more decompositions exist.
