Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8673278, here are decompositions:

7 + 8673271 = 8673278
79 + 8673199 = 8673278
151 + 8673127 = 8673278
157 + 8673121 = 8673278
181 + 8673097 = 8673278
241 + 8673037 = 8673278
331 + 8672947 = 8673278
409 + 8672869 = 8673278

Showing the first eight; more decompositions exist.
