Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672280, here are decompositions:

7 + 8672273 = 8672280
13 + 8672267 = 8672280
17 + 8672263 = 8672280
41 + 8672239 = 8672280
73 + 8672207 = 8672280
79 + 8672201 = 8672280
103 + 8672177 = 8672280
163 + 8672117 = 8672280

Showing the first eight; more decompositions exist.
