Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647320, here are decompositions:

43 + 8647277 = 8647320
47 + 8647273 = 8647320
67 + 8647253 = 8647320
89 + 8647231 = 8647320
127 + 8647193 = 8647320
137 + 8647183 = 8647320
139 + 8647181 = 8647320
163 + 8647157 = 8647320

Showing the first eight; more decompositions exist.
