Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647360, here are decompositions:

11 + 8647349 = 8647360
83 + 8647277 = 8647360
107 + 8647253 = 8647360
131 + 8647229 = 8647360
167 + 8647193 = 8647360
179 + 8647181 = 8647360
233 + 8647127 = 8647360
269 + 8647091 = 8647360

Showing the first eight; more decompositions exist.
