Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672404, here are decompositions:

17 + 8672387 = 8672404
23 + 8672381 = 8672404
71 + 8672333 = 8672404
107 + 8672297 = 8672404
131 + 8672273 = 8672404
137 + 8672267 = 8672404
197 + 8672207 = 8672404
227 + 8672177 = 8672404

Showing the first eight; more decompositions exist.
