Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648328, here are decompositions:

5 + 8648323 = 8648328
11 + 8648317 = 8648328
61 + 8648267 = 8648328
89 + 8648239 = 8648328
107 + 8648221 = 8648328
137 + 8648191 = 8648328
149 + 8648179 = 8648328
179 + 8648149 = 8648328

Showing the first eight; more decompositions exist.
