Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8673428, here are decompositions:

7 + 8673421 = 8673428
67 + 8673361 = 8673428
157 + 8673271 = 8673428
229 + 8673199 = 8673428
241 + 8673187 = 8673428
271 + 8673157 = 8673428
307 + 8673121 = 8673428
331 + 8673097 = 8673428

Showing the first eight; more decompositions exist.
