Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672208, here are decompositions:

5 + 8672203 = 8672208
7 + 8672201 = 8672208
31 + 8672177 = 8672208
47 + 8672161 = 8672208
107 + 8672101 = 8672208
109 + 8672099 = 8672208
227 + 8671981 = 8672208
229 + 8671979 = 8672208

Showing the first eight; more decompositions exist.
