Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8673728, here are decompositions:

127 + 8673601 = 8673728
157 + 8673571 = 8673728
181 + 8673547 = 8673728
211 + 8673517 = 8673728
229 + 8673499 = 8673728
307 + 8673421 = 8673728
367 + 8673361 = 8673728
457 + 8673271 = 8673728

Showing the first eight; more decompositions exist.
